95% of the windows we do are after pressure washing the building. All the dirt and cobwebs are off the windows and window seals. Could I just do an additional rinse with purified water to eliminate the spotting, I stead of a full wfp cleaning? On my quote we clearly state WFP cleaning only, no restoration or hard water spot removal included. I do not do any inside windows at all. 90% of the time the situation is commercial buildings and office parks. Thanks so much in advance.
It could work well, though I feel just rinsing the glass with pure water may no
do the trick. Most glass needs at least a little bit of scrubbing . But even with scrubbing it will be
way faster than mop and squeegee.

Most glass will still need some agitation, even after power washing. Also, if you’re rinsing with the pressure washer instead of the wfp, there’s a much higher chance of dirty water seeping out from seals or somewhere and running down the glass.
Btw, I’ve tried it, and not been thrilled with the results

If you state WFP cleaning then I would just Do it that way.
I’m sure you could get away with just a pure water rinse sometimes , but as long as your charging right just do it.
I will change it up to Pure Water Cleaning if it works. Got a quote to rent some big DI tanks. Does a total cost of about .05 per gallon seem about right? Sorry for the questions but we do 98% commercial pressure washing. Trying to get better and more efficient at the window cleaning end of things.
Completely dependent on the TDS of your water source. Also might depend a little bit on what types of dissolved solids make up that TDS; I believe certain types are “heavier” and will exhaust resin more quickly.
I’d be a little surprised if I spend 5¢/gal on resin, but I’ve never done the math. I have really good water here, 35-45 ppm.
The way I look at the window cleaning (post pressure washing), is that the wfp is a necessary part of it. If you charge correctly for the windows and have a decent pole & brush setup, you should be making just as much per hour with that wfp as you do with the power washer.
The problem is that with a pure water rinse I’d say your going to be using a lot more water than as if you were using the pole with a brush.
The one thing with wFP after power washing is you can move a lot faster an scrub less.
I would say one pass with the Brush instead of two . Use a over head sprayer , an you can fly through the windows.
I wouldn’t stress using a WFP as to just rinsing with water yes it’s less labor intense , but if your getting paid well the money just think about the money while your doing it. Put on some good jams an get to it, Or hire a guy
I have a Friend who’s 98% PW you have to see the window cleaning prices he gives. He doesn’t care if they say no to the Windows.

I appreciate everyone’s input. Majestic - what is the over head sprayer you speak of? I am probably like your friend, I price it high so that they won’t have me do it!! And when they do, it is a really nice bonus!

I’m guessing he means something like this:
Is there any advantage or disadvantage to the amount of water used when cleaning with a WFP? Mainly concerned with speed, cost of water is not a concern as I use di only and it’s pretty cheap.
If after washing a building would I be able to.go faster with 4gpm, just doing a quick brush and rinse than 1gpm? Or is more water not always a good thing? Thanks, new to the window side of things.
