Preventing Bathroom Mildew
I read with interest your column about proper ventilation to prevent bathroom mildew. We have been plagued with black, yellow, and pink mildew in a tiled shower stall in our master bathroom for years. A plumber recommended that we install an exhaust fan. It doesn’t do a bit of good even though we use it every time we shower. Any suggestions?
Thoroughly clean up any mildew with a solution consisting of 1/3 cup of laundry detergent, one quart of liquid chlorine bleach, and three quarts of warm water. Allow the solution to sit until all of the dark stains have turned white. Flush the area with fresh water and towel it dry. After the process check to see if any mildew remains below the caulking. If so, the caulking should be removed, the area should be cleaned with the bleach solution and new caulking should be installed. CAUTION: Even though the solution is mild, wear safety goggles, rubber gloves and be sure plenty of ventilation is available. Never mix bleach with ammonia. The combination can be lethal.
As an added measure of protection, towel dry the shower after each use.
