Siding Maintenance & Cleaning Tips

Cleaning Your SidingSideOne Exteriors

Vinyl and concrete siding are a low-maintenance product. They require very little cleaning but it is best to do it once a year. This also allows you to take a look at your home to see if there are any bent or broken pieces that need to be replaced or repaired. You will need a water hose, soft bristle broom, and low-suds detergent to maintain your siding. Laundry detergent or dishwasher detergents are ideal, because they are low suds detergents as well as non-hazardous. There are other cleaners you can purchase, but always check that any cleaner is safe.

Do NOT use bleach for regular cleaning. Bleach will break down the mildew inhibitors in paint. Some detergents will react violently with bleach.

It is NOT recommended to use a power washer to clean siding. A power washer can force water to the back side of the siding, possibly damaging the moisture barrier or affecting the paint. The most powerful washers can peel the paint right off the your siding.

If you do get mildew or mold on the siding, you will need to use bleach to kill it. In this case, make sure you use a bleach-safe detergent.

  • Rinse the affected areas first. Make sure you use a bleach-safe detergent, and spray just the affected areas. For spraying, you can use a hand held sprayer or a pump-up sprayer.
  • Scrub with a soft bristled broom or brush if necessary.
  • Let it stand for at least half an hour (no more than two hours).
  • Rinse thoroughly to dilute the bleach. You can purchase a mildew cleaner, which will have more detailed directions.
  • After the bleached areas dry, it is best to repaint these areas to reinitialize the mildew inhibitors.
