I have some mold in the bathroom in the caulking of the bathtub and on the cloth shower curtain.
The best way to get rid of it is to use diluted bleach. I took my shower curtain and put it in a bucket of water with 1/3 a cup of bleach and let it soak all day. Then I dabbed a stronger bleach soltuion on the caulking with an old toothbrush.
It worked great and almost all the mold is gone. I just need to do this more often so it won't build up to dangerous levels.
