1. Dry cleaning products analysed and tested at the Netherlands Institute of Cultural Heritage Henk van Keulen, Suzan de Groot, Marjolein Groot Wassink, Ineke Joosten, Maude Daudin, Amsterdam, October 2009This table lists a range of cleaning products that may be used by paintings conservators. Except for the PVA sponges all products were tested dry. The products were obtained from the suppliers mentioned.The chemical content of the products was analysed. The residues on or in the surface of an oil paint layer were investigated. The handling and cleaning power of the productswere assessed based on tests performed on unvarnished aged oil paint layers. Special attention should be given to the remarks in the red rectangles; these concern specific remarks or concerns regarding the use of the products.Part of this table will be published in an article in preparation by Maude Daudin, Madeleine Bisschoff, Henk van Keulen, Marjolein Groot Wassink, Suzan de Groot, Ineke Joosten, Maarten van Bommel and Klaas Jan van den BergDisclaimer:All information in this table, from literature and our own experiments, were gathered with the best of the authors knowledge.
