Techniques for Cleaning Surface Mold
Surface molds grow in just about any damp location, such as the grout lines of a ceramic tiled shower. They\'re easy to scrub away with a mixture of 1/2 cup bleach, 1 qt. water and a little detergent. The bleach in the cleaning mixture kills the mold, and the detergent helps lift it off the surface so you can rinse it away so it won\'t return as fast. You can also buy a mildew cleaner at hardware stores, paint stores and most home centers.
Even for simple cleaning, protect yourself from contact with mold and the bleach solution by wearing a long-sleeve shirt and long pants as well as plastic or rubber gloves and goggles.
If the mold doesn\'t disappear after light scrubbing, reapply the cleaning mix and let it sit for a minute or two. Then lightly scrub again.
Seal the clean surfaces when they\'re thoroughly dry to slow future moisture penetration. Apply a grout sealer (available at tile shops and home centers) to tile joints.
Don\'t mix ammonia or any detergent containing ammonia with bleach. The combination forms a poisonous gas.
