Tub Mat

Apparently, he was one of those rubber mats in our old bathtub before we bought our house, and I can not get the little circle spots. I tried bleach, comet and others, but nothing works. We're on the floor and fix up the bathroom, so I want it to be beautiful! Suggestions?

Try lemon. Take lemon juice and cream of tartar and make a paste, then put it on the spots of fiberglass. Good luck to you and I hope it works. Also my understanding that the hydrogen peroxide applied to the spots can work too ..

Try Borax. You can mix some with warm water and wash the tank down. This is one of the Queen of Clean remedies. I use Borax for many laundering issues. It's good for the wall panels and caulk.I put in a spray bottle. Hope this helps!
