The caulk in my bathroom keeps developing black mold. I keep bleaching it, but the mold comes back. Is there any better way to kill the mold?
It sounds like someone used the wrong type of caulk for a bathtub. In this case you should completely remove all of the caulk. Use a putty knife or a 5-in-1 tool to cut and scrape away the caulk. Clean the remaining film with a rag and some bleach. Buy a Tub & Tile Caulk intended for kitchens and bathrooms, which has an added mildewcide to resist mold and mildew. Apply a continuous bead along the caulk joints, and smooth it with a wet finger or dowel. The wetness will allow it to glide over the caulk bead to smooth the joint. It may help to wrap your finger in a wet paper towel, or even mask the caulk bead with painter's tape for a uniform joint. [Non-text portions of this message have been removed]
