Tub cleaner

[rburt5]

I have a 30 year old bathtub that has dark stains/residue left over from when anti-slip things were stuck to its bottom. Is there a solvent or anything that will take it off?

Also, there is rust creeping out from around the drain. Is there anything I can do to keep it from spreading?

I attached pictures of both problems. I really don't want to tear out my tub and replace it with a new one if my old one can be saved.

30 years is a pretty good life for a steel tub. Clorox/Ajax works fairly well on steel tubs.

(I think it is by Mr. Clean) The eraser sponge pad seems to clean a bunch of stuff, and isn't highly abrasive. You might give one of those a try.

I'll try Mr. Clean's Magic Eraser and let you know how it works. Chlorox hasn't worked.
