How to Clean and Restore Faded Vinyl Siding

Clean faded vinyl siding with a mild detergent solution and soft brush, then apply a vinyl siding restorer or specialized paint to bring back its original color and protection.

  1. Assess Damage, Protect Surroundings. Walk around your home to assess the extent of fading and identify any damaged sections. Remove outdoor furniture, cover plants and electrical fixtures with plastic sheeting, and close all windows. Check that your garden hose can reach all areas you'll be cleaning.
  2. Mix Your Gentle Cleaner. Combine one part white vinegar with three parts warm water in a large bucket. For heavily soiled areas, add a few drops of dish soap. Avoid bleach or harsh chemicals that can damage vinyl or harm surrounding vegetation.
  3. Rinse Away Loose Debris. Start at the bottom and work your way up, spraying the siding with water to remove loose dirt and debris. This prevents dirty water from streaking down over clean areas and makes the washing process more effective.
  4. Scrub Out Stubborn Stains. Dip a soft-bristled brush or cloth into your cleaning solution and scrub the siding in circular motions. Work on small sections at a time, paying extra attention to areas with mildew, stains, or heavy fading. For high areas, use an extension pole with a brush attachment.
  5. Remove All Cleaning Residue. Spray each cleaned section with clean water, working from top to bottom this time. Make sure all cleaning solution is removed, as residue can attract dirt and cause streaking. Allow the siding to dry completely before proceeding.
  6. Restore Color and Protection. For moderate fading, apply a vinyl siding restorer with a microfiber cloth, working in thin, even coats. For severe fading, use high-quality acrylic latex paint designed for vinyl siding. Apply with a brush or roller in smooth, overlapping strokes, following the grain of the siding.
  7. Finish and Perfect Coverage. Remove all protective coverings and clean your tools immediately. Walk around the house to check for missed spots or uneven coverage. Touch up any areas as needed while the product is still workable.
