Cleaning Vinyl Siding

Cleaning Vinyl Siding

Everyone has a busy schedule but it is nice to know vinyl siding will take the least amount of time and effort to maintain. Vinyl siding gets dirty, it can be washed down with a regular garden hose. If this doesn't work well enough for you, try some of the simple instructions below.


How do I clean vinyl siding?

You can clean vinyl siding with a soft cloth or ordinary long-handled, soft bristle brush. For textured surfaces, use only a soft bristle brush to keep the grooves in the texture stain-free. For best results, start at the bottom of the house and work up and rinse the cleaning solution completely before it dries. If your house has brick facing, cover the brick so that it is not affected by the runoff.

Can I use a power washer?

Yes, though you should read the washer instructions carefully before use. When cleaning, hold the power washer straight at eye level to keep the water on top of the siding where it can clean most effectively. Do not aim the power washer upward as water may be driven behind the siding. Pay special attention when using pressure washers around any opening in the wall, such as windows, doors, electrical wiring, and plumbing.

Removing grime from siding

To remove soot and grime found in industrial areas, wipe down the siding with a solution made up of the following:

  • 1/3 cup (2 2/3 ounces) powdered laundry detergent (e.g., Tide® or equivalent)
  • 2/3 cup (5 1/3 ounces) powdered household cleaner (e.g., Spic & Span® or equivalent)
  • 1 gallon (128 fluid ounces) of water

If mold and mildew are a problem, use the above mentioned solution and add 1 quart liquid laundry bleach.

Cleaners for more stubborn stains

A list of commonly accepted cleaners is provided below. Be sure to spot check any general or stain specific cleaner before using it on a large section of siding. After removing the stain, rinse thoroughly with water. Do not use cleaners containing organic solvents, undiluted chlorine bleach, liquid grease remover, nail polish remover, or furniture polish or cleaners. They can affect the surface of the siding.
