I dropped some hair-dye on toilet seat (molded plastic)- help!

Have you tried comet liquid spray with bleach ? Have you tried peroxide ? How about rubbing alcohol ? Or powdered comet?

You can try some nail polish remover but it may also remove the glossy finish. Mix a little water with baking soda to make a slurry and rub the stain with a cloth. Try substituting hydrogen peroxide with the baking soda. You can also try spraying hair spray on the stain and wipe off. White toothpaste (not gel) on a damp cloth rubbing in a circular motion.

Oh, oh. Good luck with that. You might have to invest in a new one.

Have you tried rubbing alcohol yet?

Hair dye on plastic is a disaster. Get a new one.

try bleach on a cloth soaked and let sit

Thanks... will try

I used Clorox Cleaner + Bleach. It totally worked. I sprayed a little on each spot, let it sit for 15-20 minutes, and the spots are gone.

This just happened to me. I used Bon Ami cleanser and a Magic Eraser. Worked right away with no soaking.

Magic eraser , bleach and a plastic scouring pad ! I got hair bleach powder that was mixed with 40 volume developer on my white toilet . My toilet seat is also not plastic it is wood but painted and glazed to look like a hard plastic . Anyway . This bleach has been on there for weeks ...at least 3 . I didn’t think it was a big deal so didn’t hurry and try to wipe it off. Well obviously that caused an issue . You need to dip you magic eraser in some bleach , and then you need to wipe the stain. Then you need to scrub hard with the plastic scouring pad ....first one one directions and then in the opposite . Circular motions work best . Then scrub again wit the magic eraser . Keep doing this back and forth until it’s gone .

see photos . Took me just a few minutes ...like 10.

Use Bon Ami

Rubbing alcohol and baking soda!

Magic Eraser with comet cleanser may work.

They're very inexpensive. Here's how to install it. https://www.exquisitelyunremarkable.com/2021/06/how-to-replace-a-toilet-seat.html

Hyrodgen Perxiod and baking soda make a poor man's oxyclean.
