Bleach stains on bathtub
My son just moved into an apt., and the tub area was a mess. I suggested he spray it with Clorox Cleanup. He did, but he didn't rinse--and now the tub is a nasty yellow-brown. He's tried vinegar, CLR, peroxide, several products. He thinks the tub may be fiberglass because there's a crack at the drain (great apt., huh?). But he also noticed what look like paint drips. I haven't been invited to see view the disaster. Anyone have any suggestions for getting out bleach stain?
