-The first thing you'll notice is I am using a 6" razor to scrape off some exceptionally thick residue that was on the glass. This gives me a super smooth surface to work on. (Of course, I mop the glass first so the razor can glide across it.)
-I mop it again, and then I like to pre-wipe the frames of the window. This cleans the frames and also safeguards from accidental smears on the clean glass with my sill towel later.
-Now squeegee. I'm using an 18' brass channel squeegee with the fan technique. The squeegee's job is to actually "rinse" or dry the glass. The soap/water agitates the dirt and grime on the glass and combines it into the solution. The squeegee then pulls that grimy liquid clean off the glass... if you do it right!
-I use my sill, or "Dirty" towel to wipe the bottom frame, which is the wettest.
-Now I use my detail, or "Clean" towel to remove the last bit of solution which the squeegee can't get from all four edges of the glass pane.
-Done. Glass and frames sparkling.
* We mainly service low-rise residential clients, but this day we had the opportunity to work on a 10th floor condo unit with catwalk in the Stadium district of Tacoma. Very fun!
