I am in desperate need of advice and suggestions for my bathtub. We recently renovated our bathroom top to bottom and my spouse, when doing the tile floor, used our brand new bathtub to clean off the sponge. The tile is black and so is the mortar, so now we are left with a greyish stain in the tub. I have tried goo-gone, bleach and cleaners, but cannot get the stain off. It really bothers me b/c the bathroom is beautiful until you open the shower curtain
