I found my baby dress. I guess it's antique now, since it is about 62 years old. It has not been stored properly and has turned a horrible brown with aging and probably some airborne contaminants. The worst of the brown came out with soaking in Woolite 3 times, then using Simple Green and soaking again with Dawn in the water. I really would like to get out most of the rest of the brown, (really dark near cuffs and collar) but don't want to add any bleach to the water, as there is some really delicate pink hand embroidery on the collar and down the front of the dress. Anybody have any ideas? The fabric is very fine, very thin, cotton I'm sure. Any help would be greatly appreciated.
