How to Clean UPVC Window Frames

Nothing is more frustrating than cleaning your windows and seeing soil and stains clinging to the frames. Harsh chemical cleaners can damage UPVC, or vinyl, frames, leaving few options for cleaning alternatives. Clean with an all-natural solution of vinegar and water followed by an application of gloss to restore shine.


Open the windows you are about to clean and vacuum the tracks. Remove all loose dirt and debris.

Mix one-fourth cup white vinegar with three cups of hot water in a plastic spray bottle.

Spray all parts of the UPVC window frame and track. Let solution sit for two minutes and wipe with a clean, damp rag. Inspect the window frames for scratches, stains and cracks as they dry.

Brush on PVC gloss with a small paint brush or sponge. Pay special attention to any areas with heavy stain or scratches. This will make older window frames look like new.

Follow the drying instructions on your PVC gloss product. Wipe away any excess that has transferred to the windows with a damp paper towel before it dries.

Close windows and spray them down with glass cleaner. Wipe dry with paper towels.
