Begin mold cleanup only AFTER the moisture problem that caused the mold is properly addressed. Mold cleanup should be exercised with caution. Exposure to mold can occur during the cleaning process because airborne mold particles typically are released during the cleaning of mold-damaged materials. If you have allergies to mold, it is best to have someone else clean up the mold. If you have an extensive amount of mold and you do not think you can manage the cleanup on your own, you may want to contact a professional who has experience in cleaning mold. If you choose to do the cleaning yourself, take steps to protect yourself and others during cleanup:
- Have sensitive people leave the building while the work is being done.
- All workers should wear proper protective clothing (clothing that can be cleaned thoroughly or discarded), gloves, goggles and a dust mask or other breathing protection.
- Seal off the area as much as possible. Cover any air vents to prevent disturbed mold particulates from entering the ventilation system.
- Remove any furnishings from the area for later cleaning.
- Provide added ventilation (open window, etc.) if possible.
- Use a HEPA air filter in the work area if one is available.
- Remove all porous materials that have been inundated with mold growth and cannot be cleaned thoroughly enough to kill and remove all remnants of mold. Bag all materials for removal from the home before they are taken out so that mold particles are not spread during the removal process.
- Scrub any non-porous or non-removable surfaces with a mild non-ammonia containing detergent and dry it quickly. Apply a disinfectant (1 cup of bleach to a gallon of water) to the affected areas after the mold removed; apply (use a sponge or a sprayer) the disinfectant solution to the area and allow to air dry. Repeat the application of the detergent and disinfectant as necessary to kill and remove all mold residue.
WARNING! Never mix bleach with ammonia!
- Clean the area with a vacuum. Use a vacuum with a high efficiency particulate air (HEPA) filter if possible.
- Clean or discard any materials (tools, rags, clothes, etc.) used during the mold cleanup process.
- Clean any furnishings that were removed from the area earlier.
Make sure the area is completely dry and will remain dry before replacing any building materials. It is often better to wait before rebuilding, if practical.
