Toxic Black Mold - Mold Growth and Cleanup

Mold Growth and Cleanup

No one should attempt to clean mold or mildew without wearing rubber gloves.  Sensitive people should wear a dust-resistant facemask or carbon filter respirator.

If the mold patch is less than a foot square, it can be removed with a chlorine bleach solution (one cup of bleach in one gallon of water). Never mix bleach with other cleaning materials, period.  It is difficult to tell what cleaning materials contain ammonia, and bleach mixed with ammonia creates a toxic gas.

The mold should come off with simple gentle scrubbing.  Do not scrape a mold that has dried because this could release mold spores into the air, where they can circulate through your air-conditioning or heating system and land elsewhere.

Once you have washed away the mold, the area should be dried completely.  Make sure to remove or repair any sources of excess water, such as leaky plumbing or a faulty roof.

Absorbent materials (such as ceiling tiles and carpet) that become moldy may have to be replaced.

If the moldy area is larger than two feet square, you should seek professional assistance or call your local government health agency for guidance.
