To remove stains from vinyl siding, clean the siding with vinegar or oxygen bleach. Regular cleaning can help prevent new stains from forming. Cleaning the siding may require a weekend, depending on the size of the home and the severity of the stains.
- Clean small stains with vinegar
To clean vinyl siding with vinegar, mix 3 cups of white vinegar with 7 cups of water. Apply the vinegar mixture to small mold or mildew stains, and scrub the stain gently with a cloth or cleaning brush. Rinse the area thoroughly after cleaning.
- Clean large or dark stains with oxygen bleach
Mix a cup of powdered oxygen bleach in a gallon of warm water, and stir the solution until the oxygen bleach is dissolved. Apply the solution to the stained area, and scrub the stain with a long-handled brush or soft cloth. Allow the solution to remain on the siding for up to 10 minutes before rinsing the area thoroughly.
- Clean the siding regularly
After cleaning, maintain the appearance of the siding by cleaning it regularly. All-purpose household cleaners can be used for regular maintenance. Begin regular cleaning at the bottom of the siding, and work upward in small sections to ensure a streak-free surface after cleaning.
