Clean tough stains off
with a nonabrasive
cleaner that won't damage
the surface of the vinyl.
Vinyl siding usually cleans up
easily with nothing more than
soap and water, and a yearly
scrubbing will keep it looking new.
For basic cleaning, use general-purpose
cleaner mixed with warm water.
Apply it with a soft-bristle cleaning
brush, scrubbing the full length of each
lap (Photo 1). Start at the bottom to
avoid streaking, and use your garden
hose to rinse off each section before it
For tough spots like paint drips, tar,
and pencil and pen marks, use a nonabrasive
bathtub cleaner or nylon scrub
pad (Photo 2). Use ammonia cleaners
or a solution of 1 part bleach in 4 parts
water to clean mold and mildew stains.
(However, never mix ammonia and
bleach.) Rinse thoroughly while the
siding is still wet.
Don't use paint thinner, nail polish
remover, spot removers, paint remover,
straight chlorine bleach or furniture
cleaner on vinyl. These types of cleaners
can damage the surface of the siding.
