How to remove stain on refinished bathtub
i placed a new rubber mat with suction cups on my sparkling white refinished tub. Two days later, I lifted the mat to give the tub its weekly cleaning. I found the pattern of the mat on the tub in a light brown color and NOTHING I have tried so far has removed the stains. Because the tub has been refinished, I am not supposed to use anything scratchy on the tub surface, and I never have. The refinishing company is no help. Here are the things I have tried:
1. Peroxide soak overnight, rub with soft sponge.
2. Vinegar and baking soda applied with soft sponge.
3. Straight chlorine bleach soak with white towel to retain the Bleach. Left on 2 days.
Can you help me, please? THANK YOU’
