Color transfer from shower curtain

[HansieMom]

I have a shower curtain with intensely colored squares of blue, purple, green etc. I like it a lot. But it has transferred splotches of pink color to my fiberglass bathtub. They resist removal by normal bathroom cleaners.

Do any of you have ideas on what might work to remove these stains?

MN is my favorite forum of this type, and I may be asking the impossible because I live in U.S., but anyway, any ideas? And has this ever happened to any of you? I ordered a white shower curtain with clear top, and will try to get the tub clean in the days before it arrives.

Have you tried a cream cleaner and non-scratch scourer? Fibreglass responds well to a mildly abrasive type of cleaner.

I read about one--soft with bleach in it, and I will get one of those. I googled hair dye on fiberglas as I figured that would be similar, and someone mentioned Sol U Mel, I think, which is environmentally safe, and I ordered some of that from Amazon. Who knew a vivid color shower curtain could stick to a damp tub and discolor it? it is actually dark blue,blue and purple, no green.

I fixed it! I ordered Soft Scrub gel with bleach from Amazon as apparently it is hard to find. I scrubbed it without seeing much if any effect, then left the suds on, went back an hour later and almost all the stain is gone!
