The all-purpose cleaner used by professionals prior to painting exterior surfaces. It removes mold and mildew. Also de-glosses surfaces that are oil-base painted. Ideal for cleaning garage or basement floors. May be used to restore dried, used paintbrushes. For normal cleaning jobs and the removal of mold or mildew on exterior surfaces, mix 1 cup of T.S.P. with 1 gallon of warm water. For heavy cleaning, double the mix ratio of T.S.P. to 1 gallon of water. Scrub areas, from the bottom up, with a sponge or stiff brush. Rinse thoroughly with clean water. Do not mix with bleach.
