Dear Colleagues Last year I attended the cleaning workshop given by Dr. R. Wolbers at the NATCC. Following the information I could get Tritón XL-80N but only in a small quantity because Sigma here only works with investigation programs and dont sell another quantity. Does anyone has experience working with it? is there a specific concentration for this surfactant or you can use the suggestion 0.5-1.0 g/l (Chemical principles of Textile Conservation by Agnes Tymar-Dinah Eastop) ? I principaly will use it for tapestries cleaning.
