We recently had a new acrylic tub installed and the contractor put a few dings in it. In his attempt to fix it, he was able to almost remove the scratches, but we are left with gray smudges in two places. They do not appear to be residue and we have tried cleaning with warm water and soap, but are hesitant to try any harsher chemicals. I reached a nice settlement with him over it, but we are trying to avoid reglazing a brand new tub. Any idea what the marks are or if they can be removed, or spot glazed?
