Ok I am back with another problem!! I have a porcelain tub that I took up some of those grip sticker out of. Now I can see the real color of the tub and I am trying to get it back to that color. We tried a lot so far so I will list what we tried on it!! Kaboom for tub and tiles, Bleach, Mold remover, Comet, and some type of bubble spray. None of these worked and I was wondering if anyone knew of some good stuff to try!! Open to just about anything, except replacing the tub!!!! Thanks!!
