Because I need help!
I have an adorable white sweater which inexplicably became discolored on the lower arms after I washed it. Well, not inexplicably. It appears to have had a reaction wherever my skin touched it -- a reaction to sunscreen? It's 80% cotton, 20% nylon. I know you can't use regular bleach on nylon.
I've tried Clorox 2, Woolite, borax, and am headed to the store for some Oxyclean next. If that fails, lemon juice and sunlight.
Any other suggestions?
