Prevent Mildew
Molds that cause mildew are
always in the air but need mois
ture and certain temperatures
to grow.
Mildew will grow on anything
from which it can get enough
food including leather, plaster
ed and painted walls, wallpap
er, and upholstered furniture.
Prevent mildew by removing
dampness Allow clothes to dry
before storing them in a closet
or putting them in a hamper.
Leaving a light burning in
the closet or using an electric
fan or heater in damp areas will
also reduce risk of mildew.
