How to Clean UPVC

Updated February 21, 2017

Unplasticized polyvinyl choloride, or UPVC, is a rigid and chemically resistant plastic used often in window and door frames. UPVC windows and doors are made to last longer than wood, provide better insulation and clean easily. UPVC is also more resistant to extreme weather and dampness, and UPVC windows are generally double paned, offering more savings in the form of less energy loss. These products are easily cleaned; do not use any harsh abrasives.

  1. Open the windows and doors. Sweep or vacuum out all the tracks and grooves to eliminate loose dirt and build-up. Close the windows and doors.

  2. Mix 1 cup white vinegar with 4 cups hot water in a large spray bottle.

  3. Spray the window or door frame and glass. Leave on for two minutes.

  4. Wipe with a clean, damp cloth.

  5. Apply a PVC gloss to the window or door frame, using a small paintbrush or sponge according to product instructions, to restore original shine.

  6. Wipe out excess product using a damp paper towel and dry the window or door frame according to gloss product instructions.

  7. Clean the window or door glass with a glass cleaner. Wipe using paper towels.

  8. Repeat for all other UPVC windows and doors requiring cleaning.

  9. Tip

    Substitute lemon juice for white vinegar. Baking soda on a damp piece of cloth also cleans UPVC.


    When cleaning UPVC windows and doors, do not use detergents or scouring pads, as they may scratch the UPVC.
