Have you tried calling a place that sells those tubs. That would be your best bet. You don't knpw what the coating is on the tub and might damage it

Ok thanks

Bleach takes time to work. Did she add some bleach to water, plug the drain, and let it sit for a number of hours? I'd be shocked if that doesn't work.

I'd also try Magic Eraser.

Get some Rit dye remover made for removing fabric dye.

Putting a drunk person in a tub of water is a dangerous idea. First of all, it is NOT going to get them sober any faster. Second of all, you risk them drowning.

Thanks for all of the ideas. I will let you know if any of them work. She did try letting bleach sit in the tub overnight and that didn't work. I agree with not putting a drunk person it the bath or shower.It doesn't help. It can only cause problems.

My Mom used to spread paper towels on the bottom of her tub, then pour straight bleach over them. Left the soaking towels for several hours, with the door closed to keep the fumes in, , then removed and simply rinsed the tub.

I believe you need some professional cleaners for cleaning that stains off your bathtub. It seems to be very deep stains. Or one thing you could do is go online for cleaning companies like cleaningcompany.ae and check out their methods of cleaning or some tips.

Sometimes the only thing we can do to remove stains in the bathtub is pumice stone. Just get it a little bit wet and it won't hurt the tub at all. In addition, it is totally safe for kids and pets to be around. I would give that a try.
