Window Cleaning Soaps: A List of Professional Window Cleaning Chemicals Developed for Squeegee Use, Why We Use Them & Who Manufacture’s Them

For starters, I recommend the use of a professional window cleaning chemicals over “homemade recipes” because, I want to diminish the risk of permanently damaging glass surface.

With the wrong mix of chemicals used when cleaning a specific type of glass surface, a window cleaner can cloud glass, damage treated glass and harm window surroundings i.e.. (window frames, caulking and paint).

Liability is a big issue, and the reason, I trust the recommendations and use of professional window cleaning products. Most of the time, window cleaners and residential or commercial clients don’t have the time to research the window manufactures recommendations on how to clean their particular type of glass. So, the need for a safe product becomes a must!

Generally speaking, professional window cleaning soaps are just that…

…Soap! Nonabrasive, environmentally friendly, contains no solvents, ammonia, or alkali, many types are biodegradable, designed to clean and naturalize the P.H. of most window glass surfaces.

If, there is one window cleaning soap that many window cleaners around the world use that isn’t designed by a window cleaning chemical manufacture, I’d say it’s common dish washing soap i.e.. (Dawn or Joy). I’ve used common dish washing soaps in a pinch but, prefer a professional product because, professional products are formulated to work better with a squeegee…


…And that means – “Low Suds”! Suds, or soap bubbles, can reek havoc when squeegeeing dry a pane of glass, it may leave streaks and, common dish washing soap is more prone to “Bleeding”.

If you’ve ever squeegeed a pane of glass dry and noticed the corners of glass, and any steaks you might have left behind, begin to “Spider across dry glass”, that’s called soap bleed.

Soap bleed usually occurs on windows that are encased in vinyl frames. Vinyl in partly made of oil, and as the vinyl ages and deteriorates, it leaches oil onto the glass. The combination of your window cleaning soap and the leached oil produces a bleeding effect after you’ve squeegeed dried the glass.

So, finding the right balance between soap and water is essential to reduce bleeding at the same time leaving the glass slippery enough to turn squeegee blade across without squeegee rubber dragging. Check out the “Super Swirl” window cleaning technique for advanced squeegee techniques.

Another way to eliminate soap bleed is to seal the glass using a glass sealant. Check out my article on glass sealants for more info.

Purpose of Soap

The main purpose we use soap and water to cleaning windows is, to loosen dirt from glass and to keep glass wet and slippery long enough to squeegee entire surface. This requires a chemical that will hold water on glass, which is the necessary property soap provides. Slow drying is the key — NOT fast drying!

TIP: On hot days, you can slow waters evaporating effect on window glass by adding a few drops of squeegee friction reducer to your bucket soap and water.

The other reasons we use soap instead of a quick drying chemical like… (Ammonia), is it extends squeegee rubbers life by reducing drag and friction.

Standard Window Cleaning

Standard window cleaning involves scrubbing cleaning solution on window glass with a strip washer or professional window cleaning brush, and squeegeeing dry glass. If stains and other surface contaminates still exist after standard cleaning, glass restoration is needed.

Glass restoration is a completely separate service than standard window cleaning and you’ll need to add labor and supplies charges accordingly to your customers invoice; make sure to approve this additional service with your client before proceeding with restorative processes.
