If any black mold is found within a home, it should be immediately removed. Otherwise, it can grow out of control and take over the residence. This toxic substance can cause serious health issues for those who are exposed to it. Commercial businesses exist that specialize in killing and removing mold but the homeowner can save money by trying to kill the black mold him or herself. The individual should wear a respirator or dusk mask with a medium or high efficiency filter and protective clothing that covers all areas of the body. He or she should also wear eye goggles and rubber gloves. The clothing should be removed inside the work area once cleaning is complete. It should be washed separately or placed in a heavy duty garbage bag and disposed.
Step 1: Resolve moisture problems. Identify where water is accumulating and fix the leaks. Remove any standing water and allow the area to dry, moving any wet items to a place where they can dry separately. Black mold can begin growing within 24 to 48 hours, so act quickly.
Step 2: Use a humidity sensor to determine the relative humidity of each room. If a room has a 55 percent or higher relative humidity, purchase a dehumidifier for the area.
Step 3: Seal contaminated areas. Prevent the mold from spreading prior to cleaning and removal. Mold can become airborne during cleaning, so contain the areas that are being cleaned and minimize dust that can transport mold spores. Cover vents, doorways, and other openings with plastic sheeting secured by duct tape. Put an exhaust fan next to an open window or door to outside, away from an air exchange. This will direct the air outside. Turn off the HVAC system and use an air purifier to minimize airborne particulates.
Step 4: Clean the mold. Clean each room separately, one by one. If the surface is dry, spray a light mist of water on it before cleaning, to prevent the mold sports from becoming airborne. Clean the area with soap, removing as much mold as possible. Apply a disinfectant that kills mold spores. Clean all surfaces located in the area, even if mold cannot be seen. Let the area dry completely.
Step 5: Any porous items that have extensive damage should be removed and replaced. This may include clothing, furnishings, insulation, wall board, ceiling tiles, carpet, and books.
Step 6: Place mold and mold-infested items into a heavy duty plastic bag. Take the bag directly outside through a window or door in the room being cleaned. Do not carry the bag through the rest of the home because the mold may spread. Do the same with the bag of work clothing. Transport the bags to a landfill.
Step 7: Re-inspect the area for additional signs of moisture leakage or mold growth. If these are found, the problem may be stemming from another location and should be addressed by a professional.
