How to Clean Vinyl Siding
Even though it’s relatively easy to clean vinyl siding, you’ll want to observe a few rules so that you do not damage your expensive purchase:
Q: Do I have to use a power washer?
A: No. For mild cleaning, you can use a garden hose and long-handled, soft-bristle brush if you wish.
Q: But can I use a power washer if I want to?
A: Yes, but be careful. The danger of using a power washers is this: 1.) the powerful jet can damage the siding because vinyl siding can easily break; 2.) forcing water behind the siding.
Q: How can I avoid the danger of using a power washer?
A: Stand at a reasonable distance from the siding (5-6″) and make sure that the spray is always level to the siding. Do not aim the power washer upward at the siding.
Q: How can I clean mold and mildew?
A: No special vinyl-cleaning liquids are required! You have three options:
For small spots, use Fantastik or Windex.
For larger spots, a solution of 30% vinegar and 70% water will work just fine.
Or for very stubborn larger spots, use a solution of 1/3 cup powdered laundry detergent, 2/3 cup powdered household cleaner (like Spic and Span), 1 quart liquid laundry bleach, and 1 gallon of water.

- Bubble Gum: Fantastik, Murphy Oil Soap, or a solution of vinegar (30%), water (70%) and Windex.
- Crayon: Lestoil.
- DAP (an oil-based caulk): Fantastik.
