I replied at length privately, but water is BAD for emulsions unless you're ready to go through a complete re-soak. Unless the re-soak ends in a bleach bath, it's probably not going to help, and could make matters worse. There are some very good sites that discuss photo material conservation/restoration and the appropriate materials and protocols. http://www.cr.nps.gov/museum/publications/conserveogram/cons_toc.html http://www.mnhs.org/preserve/conservation/photographs.html
the USA library of congress web site also has some good references. I actually quoted a higher RH to him for storage. It seems 30-40%RH is now considered best. Last I heard it was 60% max PEC-12 is best to use if you need a cleaner. jim On Sat, 2004-03-20 at 19:22, Carol Spears wrote: > On Sat, Mar 20, 2004 at 08:33:09PM -0500, Gary Montalbine wrote: > > I have some 40 year old 35mm slides and negatives that have mildew > > on them.
