Caring for Exterior, Painted Wood
Superficial surface dirt can be removed by washing painted wood exteriors with water and a soft-bristled, long-handled brush (such as those used for washing cars). Heavier accumulations can be removed with a mild solution of household detergent. Other cleaning solutions consisting of alcohol/water mixtures are also effective.
As with any cleaning operation on a vertical painted surface, streaking will be minimized if the surface is washed from the top to the bottom. Always rinse the surface well with clean water to remove excess detergent solutions or cleaners. Prolonged detergent contact with paint can cause damage to the finish.
Grease or oily materials may require the use of stronger cleaning compounds. Solvents or abrasive-type cleaners should be avoided. Do not allow strong detergents, ammonia, chemicals or other harsh cleaning substances to come in contact with finished exterior surfaces as they can cause damage.
Small damaged areas in the painted finish, such as nicks and scratches, may be touched up with a matching, high-quality latex primer and paint. Contact your local paint supply store for product recommendations and instructions.
Inspect the exterior caulking around the outer edges of the window frame. Trim off any old, loose caulking and seal any gaps with a good quality caulk.
