In my shower along the bottom where wall and shower tile floor meet, I have a strip of silicon caulk. There are some black colored spots I think are molds which I periodically use chlorox to clean and it keeps coming back. I never really paid too much attention to it until...recently I came across some reading materials about toxic black molds...and how it can destroy someone's immunity system and cause respiratory problems and allergy etc...I started to worry may be I should have mold test to see what I have? Could it be I have a serious mold problem? The mold seem to be on (or in the back of) the caulk. I do not see any on the grout joints. I also see a few spots along the caulk line that is between the bathroom tile wall and my pedestal sink. Also in my kitchen near the sink, against the wall, where the back splash meets the counter top, same thing, water always splash there.
Does it mean those are molds on the surface and cleaning it will take care of it? Should I continue to use Chlorox periodically as they come back to "control" them or is there a way to solve or eliminate this problem? Does it mean I have a bigger problem behind the bathroom walls? I don't want to over-react but I don't want to take it lightly either, I normally research things on the net and what I read scares the crap out of me!
I have an exhaust fan in the bathroom but apparently it did not help the situation much. Location is Miami - the humidity capital.
Any advise?
