Getting rid of chemical stains on floor

[Jockos]

Hi all!

I found some yellow stains on my plastic floor, I pretty sure it's fixer but it might be D76.

Rubbing does not seem to help. I tried alkaline soap, spirit vinegar (acid) and paint thinner.

Any suggestions?

pretty much impossible to wipe it out, as it's already working as an ink-eraser itself...

It can't be dissolved if I pour some more fixer over the spot and then wipe it of?

I haven't tried this but I would try some laundry oxygen soaker for babie's nappies (diapers). Sold as a powder. Main ingredient percarbonate. Make a very strong solution and leave it on for a while, and renew it frequently (because the bleaching action diminishes quickly). It is a bleach but gentler than chlorine which can be very destructive when used strong.

The problem with plastics is that they are actually a lot more porous than they seem.

Maybe you can try this product called "Stain Away", or try to find out what the active ingredients are. Scroll down on this page to look for it: http://www.techcheminc.com/miscellaneousxray.htm


This might be the same thing:
Photographers' Formulary Clothing Stain Remover - 8 oz

It's for clothing, but might be worth a shot.

The chemistry of developers is not unlike that of hair dyes - look for the ability to remove hair dye stains in the product description of stain removers...

Thanks for all the replies!

Problem is that I'm running out time, so I can't really wait for mail order. I'd rather leave the stain than potentially damage the floor with an untested method.
