I have a large doctors office to clean next week and wanted to get some opinions on these windows. In the past when I’ve cleaned buildings with these type of windows I’ve pre-wet, then immediately rinsed to keep the HW mix from tarnishing them. Is this necessary? This is over a 10,000 sq ft building and it has a ton of windows.
Best way is to do a small test area.
A lot of commercial windows that I do bead water no matter what additives I use. Then when it dries the water spots look terrible. Just add window cleaning to the price and get you a squeegee.

If you can get a pure water system and just rinse. If not a polish called Flitz works well on glass.
I’m not worried about the windows. They are having a window cleaner come in when I leave. Worried about the window frames being tarnished by my HW mix.
Prewet window areas. Do a 20ft section at a time. Apply HW mix, rinse, rinse, rinse. If you can just have a guy behind you rinsing as you go up ahead. If possible schedule it for a cloudy day.

I just clean glass, you guys know better about the frames getting damaged.
Do a test area first. If everything is good then go for it.
Keep it wet with mix or water and dont give it a chance to dry. Then rinse well when your done. If its hot out pre wet it good to cool them off.
