How to Clean Double Glazing

Updated February 21, 2017

Double glazing--or the process of sealing two panes of glass together with a layer of gas in the middle--is another term for insulated windows. Double glazing offers slightly better insulation than single-pane windows. Clean your windows with a homemade window cleaner to keep them crystal clear.

Fill a bucket with 1 1/2 cups of white vinegar, or 1 tsp mild soap and 1 gallon of water. Window manufacturer Jeld-Wen recommends using mild soap for the exterior.

Dip a microfiber cloth in the cleaning solution and wring it out. Wipe the windows working from the top down, rinsing the cloth as necessary. Clean the window frames last to avoid spreading dirt around.

Rinse off the soap solution with a clean, wet cloth or garden hose. There's no need to rinse if you used vinegar.

Dry the windows with a clean microfiber cloth. Work in one direction only. Alternatively, run a squeegee across the window, starting at the top and working down until it's completely dry.
