Sahara+ cleaning results

Ideally, cleaning should not damage work surfaces, but equipment that is contaminated with hardened, process residues are often scratched with abrasives and wire brushes.

The Sahara® Sponge is designed to remove hardened, dried process residues and stains from scratch sensitive equipment. Sahara Sponges will not scratch stainless steel, glass, aluminum and even soft plastic surfaces. The Sahara® Sponge is constructed from a highly cross linked coarse pour polyurethane foam that is cleanroom processed to achieve ultra-low particle, NVR and metallic contamination levels. The Sahara® Sponge is designed for use in ISO Class 3-8 cleanrooms. Sahara sponges are compatible with disinfectants, IPA, Acetone and DI water.

• Eliminates scratch damage, abrasive particle and metalliccontamination when cleaning hardened CMP slurry depositsfrom AMAT Re�exion®, Mirra® MESA and Ebara F-REX200 andF-REX300 polishers.

• Easily clean hardened and dried disinfectant stains with only water or 70% isopropyl or ethyl alcohol from stainless steel surfaces and equipment to prevent facility appearance audit failures in cGMP facilities.

• Scratch-free, quick cleaning of hardened active API and insipient residues from tablet presses.

• Prevent backside particle contamination by removing embedded particulates in electrostatic chucks (ESC).

• Eliminates particulate, metallic and scratch damage problems associated with Scotch-Brite™ and wire brushes.
