How to Clean Siding

Dirt, grime, and algae will build up on your vinyl siding. This happens gradually, and you might not notice it until your home starts to look dull. Following the steps for how to clean siding will brighten up your home’s appearance considerably. This chore also gives you a good opportunity to inspect your home’s exterior for maintenance issues that may have gone unnoticed.

How to Clean Siding Directions

  1. Walk around your house to see if you have any stains or algae growth.
  2. After evaluating siding conditions, choose an appropriate cleaner for the job.
    1. Basic dirt and grime will come off with warm, soapy water or a commercial siding wash.
    2. For stains, bits of paint or tar, or other marks, get a nonabrasive bathtub cleaner for scrubbing those areas.
    3. Areas with algae or mildew growth could require scrubbing with bleach OR ammonia. Use one or the other. Never mix those cleaning agents due the poisonous gas that results from their chemical reaction.
  3. Start at the bottom row of siding.
  4. Apply cleaner with sponge or soft-bristle brush, wiping and scrubbing as necessary.
    1. A nylon scrubbing pad will be helpful for removing stuck-on bits.
  5. Rinse cleaner off completely with hose spray nozzle as you work your way up the wall.
    1. Do not allow cleaner and dirt residue to dry on siding.
