How to Remove Mold and Efflorescence

Removing Mold

1). Wear protective gear so you don't inhale the mold spores, which can cause an allergic reaction and respiratory irritation in some people. A respirator, goggles, rubber gloves, and long sleeves and pants will provide protection.
2). Open windows and doors before beginning. Set a fan in the doorway to move fresh air through the area you are cleaning.
3). Scrub the affected areas with hot, soapy water. Use detergent that does not contain ammonia.
4). Rinse the areas with hot water.
5). Disinfect the area to prevent mold from coming back. Use a 10-percent bleach solution, using 1 part household bleach to 9 parts water. Wipe the area thoroughly.
6). Allow the area to air-dry for several days. You can speed drying by using a dehumidifier, running an air conditioner, or turning up the heat. All these activities remove moisture from the air.

1). Use a high-pressure water hose or a dry scrub brush to remove as much of the crystalline residue as possible.
2). Dampen any areas that still have efflorescence present.
3). Mix a solution of 1 part muriatic acid to 12 parts water, and scrub the area with a stiff brush. Always protect your skin and eyes when using muriatic acid.
4). Rinse the area with clear water, and allow it to air-dry.
