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

- 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

from the area earlier.
Make sure the area is completely dry and will
remain dry before replacing any building
