How do I clean a bathtub that has always been stained and dirty?
When the builders installed the bathtub, they tore our a paper that was on the inside of the tub and did not clean up the glue that was holding it down. Dust from building, installing sheet rock etc. got on the glue and I have never been able to get the bottom of the tub clean. We recently left water standing in it and it caused some rust looking spots that will not come up. I have tried Borax, Clorox and other cleaners and nothing will clean it. I don't want to replace it because it is built in with the walls and I cannot afford to replace the entire thing. Just want to know how to get the tub clean or refinished.
I hope someone can help me with this problem.
Thanks in advance.
