Commercial products are available for cleaning vinyl trim, but they can be abrasive and expensive. Instead, thoroughly clean your vinyl window trim with common household products.

  1. Pour 1/4 cup dishwashing soap into a quart-size spray bottle. Fill the bottle with hot water and shake the contents to mix.

  2. Spray the window trim with the soap solution and scrub the trim with a soft-bristle brush. Rinse the window trim thoroughly with cool water. Use a water hose if you have one handy.

  3. Pour 1 1/3 cup white vinegar into a quart-size spray bottle. Fill the bottle with hot water and shake the contents to mix.

  4. Spray the window trim with the vinegar solution and use a soft-bristle brush to scrub the trim. Vinegar is particularly suited for removing mildew from vinyl siding. Pour cool water over the trim to rinse the vinegar off.

  5. Tip

    Always wear rubber gloves to protect your hands when working with cleaning solutions.

    Warning

    If you have to use a ladder to reach the window, have someone hold the ladder while you’re cleaning the trim.
