In
Fall, Our Thoughts Turn to . . . Mold?
Mold spores are not only outdoors on rotting leaves and wood,
they are present indoors, floating in the air or in house
dust. As long as there is moisture present, they can grow
on nearly any surface, including wood, carpet, paper or food
items. There’s not much you can do to eliminate mold
spores, but you can prevent them from growing by eliminating
wet or damp areas. Mold not only creates health problems,
it can also damage or rot surfaces where it grows. More important,
dead mold may still trigger an allergic reaction in some people,
so you must not only kill the mold, you must remove it.
If you have a mold problem, you must fix the source of the
problem to decrease the chance of it reoccurring. Here’s
a list of potential sources:
Indoor humidity – reduce to 30-60 percent. Vent bathrooms,
washer machines and dryers. Use a de-humidifier and exhaust
fans. Prevent condensation on cold surfaces by adding insulation.
Air conditioning – Keep air conditioning drip pans
clean and the drain lines unobstructed and flowing properly.
If you suspect your HVAC system is contaminated, do not run
the system as it could spread the mold. Consult EPA's guide
Should You Have
the Air Ducts in Your Home Cleaned? and consider
having professionals clean your system.
If the mold was caused by sewage or other contaminated water,
call a professional with experience in this area.
When cleaning mold, limit your exposure by wearing an N-95
respirator, available at many hardware stores and on the
Internet. Wear gloves (household are sufficient) and goggles.
Clean mold off hard surfaces with detergent and water and
dry completely. Then disinfect these cleaned surfaces with:
1/4 cup household bleach per gallon of clean water for light
contamination.
11/2 cups household bleach per gallon of clean water for
heavy contamination.
CAUTION: Do not mix bleach with cleaning products
that contain ammonia.
If you suspect mold is present but can’t see it, it
may be hiding in places such as the back side of dry wall,
on walls behind furniture, under wallpaper or paneling, on
top of ceiling tiles, or under carpets and pads. Mold may
also be lurking inside walls around pipes, in ductwork, and
in roofing materials above the ceiling tiles. Your best recourse
is to throw out any materials that have been contaminated
by mold.
