Hello. I'm remodeling my bathroom. One of the things I'm doing is
reglazing the tub. While I was removing the caulk from the sides of the
bathtub, I noticed 1 corner was covered in black. I figured it was mold so
I poured bleach in that area and left it alone for 1 day. The following day
as I continued cleaning, I cleaned up the black stuff and it looks like
Charcoal. Can anyone tell me what this is? Maybe it really is charcoal and
some people use this to control moisture. Thanks for your help.
Could be just collection of floor dust. If it is mold, BAD/some times
dangerous stuff. Wonder if proper caulking was used(one made for
bathroom use)? May need to redo the caulking after cleaning.
