How To Reseal Vinyl Window Sashes From Oxidation

Resealing vinyl window sashes from oxidation involves cleaning, protecting, and sometimes restoring the vinyl surface. Here are some effective products and methods to help reseal and protect vinyl window sashes:

  1. Vinyl Cleaner and Restorer

Products: There are specialized vinyl cleaners and restorers available on the market. Look for products designed specifically for vinyl windows, such as:

  • Rejuvenate Outdoor Window and Door Cleaner
  • Vinyl Renu


  1. Clean: First, clean the window sashes thoroughly with the vinyl cleaner.
  2. Apply Restorer: Once dry, apply the vinyl restorer according to the manufacturer’s instructions. This usually involves applying a thin, even coat and allowing it to dry.
  1. UV Protectant Spray

Products: UV protectant sprays can help prevent future oxidation by creating a protective barrier. Some recommended products include:

  • 303 Aerospace Protectant
  • Meguiar’s Mirror Glaze Vinyl & Rubber Cleaner/Conditioner


  1. Clean: Ensure the vinyl is clean and dry.
  2. Spray: Apply the UV protectant spray evenly over the surface.
  3. Wipe: Wipe off any excess with a clean cloth.
  1. Vinyl Conditioner

Products: Vinyl conditioners can help maintain the flexibility and appearance of the vinyl. Examples include:

  • Mother’s VLR (Vinyl, Leather, Rubber)
  • Armor All Original Protectant


  1. Clean: Clean the vinyl thoroughly.
  2. Condition: Apply the conditioner with a clean cloth, working it into the surface.
  3. Buff: Buff with a dry cloth to remove any excess.
  1. DIY Cleaning and Protecting Solution


  • Mild dish soap
  • Water
  • White vinegar
  • Soft cloth or sponge
  • Baking soda (for tougher stains)
  • Car wax or polish (for protection)


  1. Clean with Soap and Water: Mix mild dish soap with water and clean the vinyl thoroughly using a soft cloth or sponge.
  2. Rinse: Rinse off any soap residue with clean water.
  3. Remove Tough Stains: For stubborn oxidation stains, make a paste with baking soda and water. Apply the paste, scrub gently, and rinse well.
  4. Vinegar Rinse: For an extra clean, you can wipe the vinyl with a solution of equal parts water and white vinegar.
  5. Protect: Once clean and dry, apply a thin layer of car wax or polish to the vinyl. This will help protect it from UV damage and oxidation. Buff off any excess with a clean cloth.

Maintenance Tips

  • Regular Cleaning: Keep the vinyl clean by regularly wiping it down with a mild detergent solution.
