Title: Watch out for that fiberglass
Review: Another reviewer said that this did not damage the fiberglass, but the instructions for use warn that some kinds of fiberglass may be affected. We have a "Lyons" fiberglass shower surround, and the area on which I tried this grout remover (an area that was going to be covered up) *was* affected: it took the gloss off in a short time. It worked fine on the anodized aluminum door frame and made the silicone caulking compound very easy to scrape off. (Now I see that ours is 2153NA rather than 2153DC-NA, and we've had it a while, so the formula may have changed -- but test first in an inconspicuous place anyway.)
