1. INSTALLATION 1.1. Fixing Principals
1.1.1. General Fundamentals
1.1.1.1. Building Material
The substrate and its quality are decisive for selection of the fixing: the building material and anchor base. A differentiation is made between concrete, masonry and panel building materials.
a) Concrete is building material containing cement, which can be divided into two sub-categories: Standard concrete and lightweight concrete. While standard concrete contains gravel, lightweight concrete comprises of additives like pumice, expanded clay or stryopore, usually with lower compressive strength. Because if this, among other things unfavorable conditions occur for anchoring fixings.
The magnitude of the bearing force of a heavy-load fixing depends, among other things on the compressive strength of the concrete. This is indicated by the numbers in the short designations: e.g. the most frequently occurring concrete strength C 20/25 has a compressive strength of 25N/mm2 when a sample 150mm cube is crushed in a test machine.
b) Masonry building materials. Masonry is a composite of blocks and mortar. The compressive strength of the blocks is usually higher than that of the mortar, especially in old buildings. Therefore, as much as possible, fixing should be anchored in the masonry block. Regarding fixing in masonry, often the bricks itself are the weakest part of the system. Therefore the exact load depends on the condition of the masonry.
Generally, four groups of masonry blocks are differentiated:
a) Solid blocks with dense structure are building materials that are very resistant to compressive loads
without cavities or with only a low percentage of hole surfaces (up to max. 15%, e.g. as grip-hole).
They are very well suited for anchoring fixings.
Solid sand-lime brick
Solid blocks, also known as brick or clinker brick
b) Perforated blocks with a compact structure (perforated and hollow checker bricks). These are mostly
manufactured from the same compressive strength materials as solid blocks but are provided with
cavities. If higher loads are introduced into these building materials, special fixings should be used, e.g.
those which bridge or fill out the cavities.
Horizontal perforated blocks and vertical perforated blocks are often termed latticed or honeycomb blocks
Sand-lime perforated blocks, sand-lime hollow blocks

crealco
c) Solid blocks with porous structure usually have a very large number of pores and low compressive
strength. Therefore, special fixings should be used for optimal fastening, e.g. fixing with long
expansion zone and fixings that engage with the material.
Solid blocks of light concrete, solid blocks of expanding clay, e.g. “Liapor”, “Gisoton”
Aerated concrete, e.g. “Ytong”, “Hebel”
d) Perforated blocks with porous structure (light perforated bricks) have many cavities and pores and
thus usually low compressive strength. In this case, special care is needed in selection and installation
of the correct fixing. Suitable fixings include those with a long expansion zone or injection anchors
with a form locking anchorage - especially with light concrete hollow blocks, with cavities that can be
filled with polystyrene.
Light concrete hollow blocks, e.g. of purnice or expanding clay
Panel building materials are thin-walled construction materials that frequently have only strength - e.g. plasterboard panels like “Rigips”, Knauf”, “LaGyp”, “Norgips”, gypsum fireboard like “Fermacell” or “Rigicell” or chipboard, hard particle board, plywood, etc. For optimum fastening, special fixings have to be selected: cavity fixing as they are called. These are fixings of plastic or metal and expand on the reverse side - fixing engaging with form locking that can anchor directly on the reverse side of the panel in the cavity.
Drilling
The building material is critical for drilling - four methods are available:
a) Rotary drilling: Drilling in rotation without impact for perforated
blocks and construction materials with low strength so that the hole does not become too large and/or the webs in the perforated blocks don’t break.
b) Impact drilling: Rotation and a high number of light impacts with
the impact drilling machine, for solid building materials with dense structure
c) Hammer drilling: Rotation and a small number of impacts with high
impact energy with the drilling hammer, also for solid building materials with dense structure

d) Diamond or core drilling process: Mainly used for large hole diameters or with greater reinforcement.
One more tip on drilling without impact: Carbide drill bits drill faster if they are ground sharp, similar to steel drill bits. There are also special masonry drill bits available.
1.2. Installation Calculations
Generally, the following aspects have to be considered during installation: The calculation of the maximum working load from the failure loads and/or the characteristics loads are carried out by dividing the respective failure loads by a safety factor:
Max. working load =
Failure load (F)
Safety factor
() Recommended safety factor Compared to the average failure load:
- Steel and bonded anchors 4
- Plastic fixing 7 Compared to the characteristic failure loads:
- Steel and bonded anchors 3
- Plastic fixing 5 Example of a steel fixing with a failure load of 40kN: FGebr. = 40kN/4 = 10kN These safety factors are standard recommendations and are only to be used for fixings if northing different is
indicated in the tables of this catalogue. With approved fixings, the safety factor can be decreased to = 2.52 by using many test series: This means that the utilization can be optimized with the use of approved fixings.
1.3. Principle of Function There are different bearing mechanisms that transfer the forces that act on the fixing into the base material.
a) With friction connection: The expansion part of the fixing is pressed against the whole wall: The outer tensile loads are held by friction. b) With form locking: The fixing geometry matches the shape of the substrate and/or of the drill hole.

c) With adhesive bond: The mortar adheres the fixing with the anchor base
1.4. Method
1.4.1. Windows
a) Using an extruded aluminium fixing lug: This allows the window to be factory glazed and wrapped. Most commonly used when the inside reveal is to be plastered after fixing, therefore concealing the lug. Use a minimum 6 x 35mm HPS anchor.
b) Using a plug and screw: Counter sunk screw-fixing through the frame of unglazed windows. This method is used to fit a window to a face-brick reveal therefore glazing and plastic wrap is done on site. Use a minimum 5 x 75mm stainless steel or plated woodscrew.

WINDOWS FASTENING POSITION
The window is fixed into position - the sill is then built at a later stage - the bottom lugs can be left in
place but it is often found that most times the mason either bends them out of its way or breaks
them off. This practically means that most windows are only secured on 3 sides.

1.9. Glazing Procedure:
1.9.1 Glass Setting Blocks
Glass-to-metal contact must be avoided at all times by using setting and location blocks having a
shore hardness of 50 to 90. Use only blocks made of Neoprene, EPDM, Silicone or other elastomeric
material.
Setting blocks are to have a minimum thickness of 3mm and must be at least 27mm in length per
square metre of glass area.
In the event of laminated glass and/or sealed insulated glass unit’s drainage is to be provided to
prevent the glass edge from being submerged. Two or more 7mm diameter holes or 5mm x 9mm
slotted holes, or larger, are to be equally spaced in the sill section of sash or frame to allow for such
ventilation/drainage.
The position of the setting and location blocks is illustrated in Figure 2.

2. CLEANING To ensure the longevity and hassle-free operation of Wispeco’s systems, the following cleaning and
maintenance procedures must be strictly adhered to.
Cleaning procedures are divided into the type of material being cleaned.
2.1. Aluminium
2.1.1. Anodised Aluminium Correctly identify the aluminium finish to be cleaned when selecting an appropriate cleaning
method. Check specifications and/or built drawings if in doubt as to finish.
Never use aggressive alkaline or acid cleaners on aluminium finishes. It is important
not to use cleaners containing trisodium phosphate, phosphoric acid, hydrochloric
acid, hydrofluoric acid, flourides, or similar compounds on anodised aluminium
surfaces. Always follow the recommendations of the cleaner manufacturer as to the
proper cleaner and concentration. Test clean a small area first. Different cleaners
should not be mixed.
It is preferable to clean the metal when shaded. Do not attempt to clean hot, sun-
heated surfaces since possible chemical reactions on hot metal surfaces will be highly
accelerated and cleaning non-uniformity can occur. Surfaces cleaned under these
adverse conditions can become streaked or stained so that they cannot be restored to
their original appearance. Also avoid cleaning during freezing temperatures or when
metal temperatures are sufficiently cold to cause condensation.
Apply the cleaning solution only to an area that can be conveniently cleaned without
changing position. Thoroughly rinse the surface with clean water before applying
cleaner. Minimize cleaner rundown over the lower portions of the building and rinse
such areas as soon and as long as practical.
Cleaners containing strong organic solvents will have a deleterious effect on organic
overlay coatings, but not on anodised aluminium. The possibility of solvents
extracting stain-producing chemicals from sealants and affecting the function of the
sealants, however, must be considered. Test a small area first.
Strong cleaners should not be used on windows and other building accessories where
it is possible for the cleaner to come in contact with the aluminium. Solutions of
water and mild detergents should be used on windows. If for some particular reason,
an aggressive cleaner is required for some other component of the building; extreme
care must be taken to prevent the cleaner from contacting the aluminium finish.

This manual must be read in conjunction with the Wispeco System Manuals and the Performance Certificates for the relevant system. Disclaimer: The right to make alterations is reserved © 2013 Wispeco (Pty) Ltd, All Rights Reserved 31
Aluminium
crealco
2.1.2. Powder Coated Aluminium: Construction soils, including concrete or mortar, etc., should be removed as soon as possible. The
exact procedure for cleaning will vary depending on the nature and degree of soil. Try to restrict
cleaning to mild weather. Cleaning should be done on the shaded side of the building or ideally on a
mild, cloudy day. Method of cleaning, type of cleaner, etc. of one component of the building must
be used with consideration for other components such as glass, sealants, painted surfaces, etc.
Over cleaning or excessive rubbing can do more harm than good.
Strong solvents or strong cleaner concentrations can cause damage to painted surfaces.
Avoid abrasive cleaners. Do not use household cleaners that contain abrasives on painted
surfaces.
Abrasive materials such as steel wool, abrasive brushes, etc., can wear and harm finish.
Avoid drips and splashes. Remove run downs as quickly as possible.
Avoid temperature extremes. Heat accelerates chemical reactions and may evaporate water
from solution. Extremely low temperatures may give poor cleaning effects. Cleaning under
adverse conditions may result in streaking or staining. Ideally, cleaning should be done in
shade at moderate temperature.
Do not substitute a heavy duty cleaner for frequently used mild cleaner.
Do not scour painted surfaces.
Never use paint removers, aggressive alkaline, acid or abrasive cleaners. Do not use
trisodium phosphate, highly alkaline or highly acidic cleaners. Always do a surface test.
Follow manufacturers’ recommendations for mixing and diluting cleaners.
Never mix cleaners.
To prevent marking, make sure cleaning sponges, cloth etc. are grit free.
2.2. Glass
2.2.1. Cleaning instructions for glass:
The following cleaning products must not be used:
Acid products
Highly abrasive products such as polish, blades or sandpaper
Water containing abrasive granules (cement etc.)
Clean warm water containing a highly diluted mild household detergent is recommended. Glass
should be cleaned often enough to prevent heavy soiling (e.g. monthly). If the glass surface is still
soiled after normal cleaning, the supplier should be consulted for remedial advice.

2.2.2. Cleaning instructions for reflective Low-E glass:
Hand Washing Pilkington Eclipse Advantage ™ Reflective Low-E Glass.
Pilkington Eclipse Advantage ™ Reflective Low-E Glass has a very thin pyrolitic coating on its top
surface. This hard and durable low emissivity top coating gives the glass improved solar control and
thermal insulation performance compared to ordinary clear glass but the low emissivity coating does
have a very fine, hard texture which requires a slightly different cleaning procedure. Pilkington
Eclipse Advantage ™ Reflective Low-E Glass can be cleaned and maintained by hand washing with
non-abrasive, ordinary glass cleaning solutions. For hand washing, a mild detergent and water
solution is recommended. Uniformly apply the solution to the glass and wash with a clean, soft
cloth, sponge or pad. Rinse thouroughly with clean water and wipe or squeegee dry immediately.
Make sure ni metal parts of the cleaning equipment touch the reflective glass surface, and that no
abrasive particles are trapped betwee the glass and the cleaning materials. Stubborn stains can be
removed with organic solvents such as minetal spirits, de-natured alcohol, acetone, or MEK,
following appropriate safety procedures. The solvent wash should be followed immediately by a
detergent wash and clear water rinse to remove solvent and dirt residues. Do not use harsh
chemical cleaners, abrasives, opaque liquid cleaning solutions, steel wool, or razo blades on the
reflective surface. Do not use any strong acidic cleaners on the Pilkington Eclipse Advantage ™
reflective coating. There are a number of solutions commercially available for ‘rejuvenating’ water-
stained glass surfaces. These products usually contain hydrofluoric acid and can severely damage
the reflective surface of Pilkington Eclipse Advantage ™ Reflective Glass. An exposed Pilkington
Eclipse Advantage ™ reflective coating will not get dirtier any faster than non-coated glass in the
same location, but the reflective surface will show dirt and other deposits more readily. The
reflective coating should never be allowed to become dirtier thatn visibly acceptable. It should be
cleaned as frequently as is necessary to prevent it from ever appearing unacceptably dirty. In this
way problems with the accumulation and hardening of excessive dirt deposits can be prevented.
Spot Cleaning:
Occasionally spot cleaning may be required to remove stubborn diet or foreign materials that can
adhere to the low emissivity glass surface. Spot cleaning products work to remove paint or markings
from grease, oil, tape adhesive, and crayons or other waxy materials as well as rub marks from
plastics.
Recommended Spot Cleaning Products:
Denatured alcohol, acetone or organice solvents available from hardware stores.
Spot Cleaning Procedure:
1. Apply a small quantity of one of the cleaners listed above to a clean, wet cloth or towel.

crealco
2. Rub on areas of glass needing spot cleaning.
3. Wipe clean using a dry, clean, lint free towel or cloth followed by the routine cleaning procedure
given above.
Specialized Cleaning:
Do not contact the low emissivity coated surface with razor blades, steel wool or other metallic
objects. If metallic objects contact the coated surface, a thin layer of metal removed from the object
may be deposited onto the coating which results in a discoloured stain which is difficult to remove
using normal cleaning procedures.
Recommended Specialized Cleaning Products for Metal Marks, etc.:
HTH swimming pool acid with 40% hydrochloric acid.
Specialised Cleaning Procedure for Metal Marks, etc.:
1. Apply a small quantity of one of the specialized cleaning products listed above to a wet, clean
cloth or towel.
2. Rub on areas of glass needing cleaning.
3. Wipe cleaning using a dry, clean, lint free towel or cloth followed by the routine cleaning
procedure.
2.2.3. Cleaning instructions for Energy Saving glass:
Cleaning Instructions for McLam® Energy Saving Glass™
This information is offered as a general guide only. Specific advice on the cleaning of glass should
always be sought from a reputable glazier or professional window cleaner before any glass cleaning
is undertaken.
All McLam® Energy Saving Glass™ products have a very thin, hard, pyrolytic coating on one
surface. This durable low emissivity coating gives them improved thermal insulation performance,
and in the case of McLam® ESG™ Grey, Green & Neutral, improved solar control, compared to
ordinary clear glass. The low emissivity coating has a very fine, hard texture which requires
a slightly different cleaning procedure compared to plain, non-coated glass.
Routine Cleaning:
Hand cleaning of a pyrolytic low emissivity coating, to visibly remove accumulated dust or
fingerprints, can be accomplished using a number of different cleaning products which are readily
available from domestic supply, grocery and hardware stores. Do not use razor blades, steel wool or
other metallic objects on the coated surface. The hard coating would probably not be damaged but

fine metal marks, looking like scratches in sunlight, could easily be left on the coating. Such marks
need special cleaning techniques to remove them – see Spot Cleaning below. Follow the
manufacturers’ recommended handling procedures for each product listed.
Recommended Routine Cleaning Products for McLam® Energy Saving Glass™ etc.:
Mr Muscle Window & Surface Cleaner, by SC Johnson & Son, Inc.
Mixture of one part clear vinegar with one to ten parts clean water.
Commercially available vinegar-based glass cleaners have generally demonstrated an ability to
provide a clean, streak-free coated surface. McCoy’s glass does not recommend the use of ammonia
or alcohol based glass cleaners because these products can leave visible streaks on the coating.
Typical Routine Cleaning Procedure:
Flood the low emissivity coated surface with a spray-on cleaning solution or with a wet cloth
saturated with the cleaning solution to thoroughly wet the surface and remove any grit
particles. Be generous with the amount of solution applied.
Rub the wetted surface with a clean, lint free towel or cloth. It is preferable not to use a
squeegee on the low emissivity surface.
To prevent streaking, stop wiping when the glass is almost dry and there is still a uniform,
thin film of moisture left on the glass surface. This film will quickly evaporate leaving a clean
surface. Note: streaking is simply the re-deposition of smears of non-uniform dirt, and
detergent from the cleaning solution if there was too much dirt and too little volume of
cleaning solution.
Detailed Cleaning Procedure to Remove Large Amounts of Dirt:
If the coated surface is heavily contaminated with dirt, such as during installation on a
construction site, use a water spray from a hose or garden spray pressure bottle to flush
away insoluble particulate matter without risk of creating fine scratches.
Flood the low emissivity coated surface with a spray-on cleaning solution or with a cloth
saturated with the cleaning solution. Be generous with the amount of solution applied.
Rub the wetted surface with a clean, lint free towel or cloth, to fully dissolve any dirt on the
coating.
Wipe dry with a dry, clean, lint free towel or cloth. It is preferable not to use a squeegee on
the low emissivity surface. To prevent streaking – stop wiping when the glass is almost dry
and there is still a uniform thin film of moisture left on the glass surface. This film will
quickly evaporate leaving a clean surface. Note: streaking is simply the re-deposition of
smear or non-uniform dirt and detergent from the cleaning solution if there was too much
dirt and too little volume of cleaning solution.
If after the above procedure, and under critical viewing, the glass does not appear clean
then a final rinse with distilled water should be made before the cleaning solution has had

time to evaporate, to remove the dirt contaminated detergent solution. This allows the final
evaporation of a thin film of pure, clean water which cannot leave any visible deposits.
Spot Cleaning:
Occasional spot cleaning may be required to remove stubborn dirt or foreign materials that have
adhered to the low emissivity coated surface. Spot cleaning products containing organic solvents, or
the one-time hand application of very fine abrasives, can be used to remove markings from grease,
oil tape adhesive, and crayons or other waxy materials as well as paint and rub-off marks from
plastics.
Recommended Spot Cleaning Products:
Methyl Ethyl Ketone, Acetone or other organic solvents available from hardware stores.
Spot Cleaning Procedure:
Use a cloth saturated with a routine cleaning solution to thoroughly wet the surface and to
remove any grit particles.
Apply a small quantity of one of the cleaners listed above to a clean, wet cloth or towel.
Rub on areas of coating needing spot cleaning.
Take particular care to prevent solvents, such as those listed above, from contacting glass
sealants, framing and adjacent paintwork.
Wipe clean using a dry, clean, lint free towel or cloth and immediately follow with the rinsing
procedure given above in “Detailed Cleaning Procedure.”
Specialized Cleaning:
If metallic objects have contacted the coated surface, a thin layer of metal removed from the object
may be deposited onto the coating which results in discoloured stains or marks that looks like a
scratch. Such marks cannot be removed using the normal cleaning procedures given above but
require the specialized techniques below.
Recommended Specialized Cleaning Products for Removal of Metal Marks, etc.:
20-30% hydrochloric acid solution – typically found in domestic liquid swimming pool acid.
Specialized Cleaning Procedure:
Use a cloth saturated with a routine cleaning solution to thoroughly wet the surface and to
remove any grit particles.
Apply a small quantity of one of the specialized cleaning products listed above to a wet,
clean cloth or towel.
Rub on areas of glass needing cleaning.

2.2.4. Cleaning instructions for Sunergy glass products:
Ordinary Cleaning Regimen:
In most cases, glass can be washed with plenty of clean water. Sometimes a bit of neutral detergent
or an appropriate commercial cleaning product can be added to the water. A squeegee or specially
designed cloths are also used. Once cleaned, the glass should be rinsed with clean water and wiped
with a squeegee.
Special Cleaning Regimen:
When ordinary cleaning is not enough, other steps can be taken:
Remove oily spots and other organic pollution with solvents such as isopropyl alcohol or
acetone applied with a soft, clean cloth.
Remove other residue by lightly polishing with a suspension of cerium oxide in water
(between 100 and 200 grams per litre).
Rinse thoroughly and then follow the ordinary cleaning regimen.
Initial Cleaning after the Glass is Installed:
When glass is cleaned for the first time after being installed (end of project), it may be particularly
dirty. We recommend the following steps:
Remove labels and cork interlayers as soon as possible.
Rinse thoroughly to remove as much dust as possible.
Perform the ordinary cleaning regimen.
Examine any remaining dirty marks.
Very carefully remove the majority of any remaining deposits of sealing compound, putty,
cement, etc. using a specially designed scraper or razor blade. There is a very high risk of
scratching the glass, so take great care at all times. This is especially true for coated glasses.
Perform the special cleaning regimen where necessary.

Special Instructions for Coated Glass:
Sunergy has a metal oxide coating that is applied to the glass. These coatings are very resistant and
durable. No particular precautions need to be taken when the coating is positioned on the inside of
the insulating glazing unit (position 2 or 3, i.e. in contact with the air/gas layer). In single glazing or
when the coating is located on the outside of the insulating glazing unit (position 1, external side of
the building, or position 4, internal side of the building),the ordinary and special cleaning regimens
described above are also suitable. However, bear in mind that a transparent and very thing metal
surface is also being washed.
Remember:
Any scratching will penetrate the surface of the coating and cannot be repaired.
Any excessive mechanical treatment might remove the coating in localised areas.
Avoid all contact with metal objects.
Avoid all chemicals that would attack the surface and damage it irreparably.
Consequently, special care should be taken to follow the guideline and precautions set out in this
document. In areas with high levels of pollution, treatments and products supplied by experienced
professionals are essential.
Hints and Tips:
All products containing hydrofluoric acid or fluorine derivatives are prohibited since they can
destroy the coating and the surface of the glass.
Highly acidic and alkaline products are prohibited, as are abrasive products.
Ensure compatibility between the products used and other components (seals, paints used
on the frame, aluminium, stone, etc.).
Comply with the instruction manuals. When in doubt, contact the manufacturer.
When carrying out the special cleaning regimen, always start with a trial on a small area.
Do not wash the glass when it is fully exposed to the sun. Avoid washing it when it is too

2.3. Stainless Steel Components:
Introduction:
Stainless Steels are inherently corrosion resistant materials that do not need additional surface
protection to enhance their appearance and durability. Some routine maintenance and cleaning is
needed to keep stainless steel surfaces in good condition so that they aesthetic appearance and

corrosion resistance are not compromised. In this respect, stainless steels are no different to other
construction materials such as glass, plastics or coated steels, which are never maintenance free
throughout the life of a building. These guidelines are to give building owners, developers and
facility manager’s advice on efficient, cost-effective cleaning that will allow them to take advantage
of the corrosion resistant properties of stainless steel.
The Self-Repair Mechanism of Stainless Steel:
First of all, it is important to understand why stainless steel is so corrosion resistant. The alloying
elements in stainless steel form a thin, transparent “passive layer” on the surface. Although this
protective passive layer is only a few atoms thick, it instantaneously reforms in the presence of
oxygen from air or water, so even if the material is scratched or damaged the passive layer continues
protecting the surface from corrosion.
This explains why stainless steel does not require any coating or other corrosion protection to
remain bright and shiny even after decades of use.
Initial Cleaning:
The first cleaning is generally done before the building is handed over to the owner. If the stainless
steel parts have been protected adequately then simple “maintenance cleaning” at the hand-over
stage will probably be sufficient. An adhesive plastic film during fabrication, transport and assembly
often protects stainless steel parts. Although providing excellent protection against damage and
soiling, some plastic films deteriorate on exposure to the ultraviolet radiation in sunlight and which
can make them difficult to strip. The film adhesive can also stick to the stainless steel surface.
Protective plastic films should be removed as soon as they are no longer needed for protection
during the installation/erection stage, starting at the top of the building and working downwards.
Motor and cement splashes can be treated with a solution containing a small amount of phosphoric
acid. Rinse with water (preferably deionised water) and dry. Deionised water reduces the risk of
water staining marks. Proprietary products are available from specialists finishing companies. Never
allow mortar removers or diluted hydrochloric acid to be used on stainless steel. If they have
accidentally been applied to or spilt over the stainless steel, rinse generously with fresh water.
Building contractors and tradesmen are not always aware how dangerous proprietary building
mortar removers containing hydrochloric acid are to stainless steel components. This should be
stressed. If possible, the sequence of operations should be changed so that any ceramic tile fixing
and cleaning is completed before neighbouring stainless steel components such as skirting boards or
kick plates are installed.
Iron particles picked up from tools or from contact with structural steel, scaffold tubing etc. must be
removed immediately.

Steel dust particles created during operations such as welding, cutting, drilling and grinding of
carbon (non-stainless) steel will rust quickly. Besides corroding themselves, these particles can
locally break the self-healing “passive film” of stainless steel resulting in pitting corrosion in spite of
their normally good corrosion resistance.
At an early stage, light deposits can be removed mechanically using nylon pads, such as the “Scotch-
Brite” type used in the kitchen. Alternatively the contamination can be removed with a proprietary
stainless steel cleaner containing phosphoric acid.
If pitting attack has occurred, depending on its severity, acid pickling treatments or mechanical
rectification will be needed to restore the surface. Pickling agents in paste form are available for
localised, on-site application. Care must be taken to use these products in accordance with the
supplier’s directions so that there is a safe system of work and the relevant legislation on
environmental protection is adhered to. Specialist finishing companies will often carry out this
service on site.
While restoring the corrosion resistance of the surface, pickling may change the surface appearance
of the steel. Further mechanical or chemical treatments may be necessary to restore the original
surface finish. It is therefore advisable to avoid contamination, in the first place by either protecting
the stainless steel parts, whilst work is being done or by installing those after other operations that
could cause contamination have been completed.
Initial Cleaning:
On external applications, such as facades, rainfall can normally be expected to wash off
accumulations of dirt and other deposits efficiently, depending on the amount of exposure of the
elevation.
Special attention should be given to sheltered areas during routine cleaning to ensure that
accumulations of airborne contaminants are removed. This is particularly important in marine and
industrial environments, where build-up of airborne chlorides or SOx can result in localised
corrosion, if not effectively removed.
On interior applications, finger marks can be an issue. There is a wide range of finishes available for
stainless steels, many of which are particularly suitable for use in heavily exposed (high traffic) public
areas. Selecting finishes that are less sensitive to fingerprint marking in the design process will
reduce the effort and costs of cleaning during the service life of the finished building.
Brushed finished, which are a popular choice for interiors, may show finger marks in the period
immediately after installation, but the visibility of the marking should become less evident after the
first few cleaning operations.

Cleansers:
To remove fingerprints and other marks from architectural finishes, soapy water or a mild detergent
are usually safe and successful. Proprietary spray cleaners are available, which combine ease of
cleaning with a light film that produces an even and smooth lustre. These spray cleaners remove
existing fingerprints and leave the surface in a condition that reduces the tendency for fingerprints
to show in subsequent service. After applying the spray to the surface, polish with a dry cloth. Your
nearest national stainless steel association should be able to advise on products locally available.
Mirror-polished stainless steel can be cleaned with glass cleansers. These products should be
selected chloride-free.
For more stubborn stains, mild household cream cleansers should be effective. This should also be
suitable for cleaning off watermarks and light discolouration. After cleaning, remove the residues
with (preferably deionised) water (available in supermarkets, e.g. for steam ironing or car batteries)
and dry to avoid streaking and water marks. Scouring powers should be not be used as these
products can leave scratches on stainless steel surfaces.
Care is needed with solvents to avoid spreading the staining on the stainless steels, which can then
be difficult to fully remove. It is advisable to apply clean solvent several times with a clean, non-
scratching cloth, until all traces of the partially dissolved oil/grease are removed.
Paint and Graffiti can be treated with proprietary alkaline or solvent-based paint strippers. The use
of hard scrapers or knives should be avoided as the underlying stainless steel surface may become
scratched.
Heavily neglected surfaces can be treated with metal polishes, such as those for cleaning chromium-
plated items (e.g. automotive trim). Furthermore, polishes used for re-finishing car paint can be
considered. Care must be taken as highly polished surfaces may become scratched with these
cleaners.
Alternatively, use a proprietary stainless steel cleaner containing phosphoric acid to remove
contamination, rinse with deionised water and dry. It is advisable that the entire surface of the
component is treated so that a patchy appearance is avoided.
Before commencing any task, ensure that you have received the appropriate health and safety
literature from the supplier and fully understand it. If in doubt, seek further advice.
Cleaners that should NOT be used on stainless steels include:
Chloride-containing cleansers, especially those containing hydrochloric acid.
Hypochlorite bleaches should not be used on stainless steels; if applied accidentally or spilt on
stainless steel surfaces should be rinsed off immediately with liberal amounts of fresh water.
Silver-cleaners must not be used on stainless steel.

Cleaning Utensils:
A damp cloth or chamois leather will usually be suitable for removing normal soiling,
fingerprints etc.
For more stubborn dirt, nylon pads such as those known as “Scotch-Brite” pads are usually
satisfactory. Non-stainless steel based scouring pads, cleaning wool or wire brushes must not be
used on stainless steel. Apart from scratching the surface, these pads can leave carbon steel
deposits on the stainless surface, which can subsequently develop into rust spots, if the surface
becomes wet.
Soft nylon brushes can be used for cleaning stainless steel with patterned finishes. Non-
stainless steel wire brushes must not be used. On “grained” directional finishes, such as EN
10088-3 types G, J and K the direction of cleaning strokes should be along the grain and not
across it.
Where water has been used for cleaning or rinsing, wiping the surface dry to prevent
watermarks, especially in hard water areas may be advisable. The use of deionised water will
prevent the formation of hard water staining.
To avoid “cross-contamination” from iron particles, ensure that cleaning utensils have not been
used for “ordinary” (i.e. carbon) steel before. Cleaning materials for use on stainless steel items
should preferable be reserved exclusively for that purpose.
Cleaning Intervals:
The cleaning of stainless steel items for building interiors is really no different to other materials.
Cleaning should be done before there is a visible build-up of soiling or finger-marking, so that the
effort and cost of cleaning is minimised along with the risk of marking altering the appearance of the
surfaces.
On building exterior applications, stainless steel may be exposed to a wider range of potentially
more aggressive environments as a result of contact with: marine atmospheres, environments laden
with industrial pollutants, salt spray from road de-icing salt, atmospheric dirt and traffic film.
All cause brown staining to appear. It is a good practice to clean the stainless steel at the same
frequency as the building’s windows (glazing). Depending on the severity of soiling and deposit
build up, routine cleaning frequencies of 6-12 months for light soiling and 3-6 months for heavy
soiling or environments such as those listed above is advisable. A stainless steel cleaner containing
phosphoric acid will remove this form of contamination.
