How do you clean the old tub mat stains in a fiberglass tub?

Question

Apparently there was one of those old rubber mats in our tub before we bought our house, and I cannot get the little circle spots out. I have tried bleach, comet and others but nothing works. We are about to tile and fix up the bathroom, so I want it to look nice! Any suggestions?

Answer 1

Try lemon. Take lemon juice and cream of tartar and make a paste and then put it on the fiberglass stains. Good Luck to you and I hope this works. I have also heard that hydrogen peroxide applied to the stains may work also..

Answer 2

Try Borax. You can mix up some with warm water and wash the tub down. It's one of the Queen of Clean remedies. I use Borax for alot of whitening issues. It's good for tub surround and caulk.I put it in a spray bottle. Hope this helps!
