I posted this on the residential spot, then realized that was for non-contractors, so if you see it there, that's why.

I'm wondering about cleaning house windows with my pressure washer, a 3700 psi, 4 gpm, cold washer. I hope to use a DI Tank to get a spotless rinse. I'm wondering if anyone's tried this on windows and what they've discovered about it. I'll try it on my own windows first, but i'm a little nervouse about possibly breaking the pane of glass with too much pressure, or not getting the window really clean. Also, has anyone washed a window right through a screen? is this effective?

Thanks,

The theory is great,but you stand a good chance of breaking the seal in the windows using to much pressure.
Washing through the screens traps trash in between the screen and window.We up sell screen cleaning as part of our service,and wipe out window frames as part of it.
Wash them with low pressure and DI if really don't want to do them by hand.

I agree with Scott...You need to stay away from the pressure around windows, especially double-paned windows. As far as washing through the screens, it might be possible, but I think the rinse time needed would remove the time saved by not removing screens.
 
There is a company here that does this. They have the customer line the screens up in the driveway...........they inject a cleaner on the windows...........rub it with a scrubber on a pole..........then rinse with di water and a pressure washer.

They then clean the screens in the driveway........and the customer deals with them.
 
thanks for the tips. sounds like i'll keep scrubbin' and squeegeing (spelling?) by hand. What i was most hoping to avoid is removing the screens, but it sounds like i'll probably have to keep doing that. I don't think i could convince too many people to deal with the screens.

In my janitorial business - we use the following method for ground level windows: We we eject chemical/water (sur-flow pump) onto the window and squeegee it off - no scrubbing with proper chemical.

For 2 to 4 story buildings - I've develop an extension out of alum piping - similar to a telescope wand (but homemade if you will) - at the end I can eject chemical or water or both - on the end I can attach a brush if needed - I basically wash from the ground - I keep the pressure at about 150 psi -- this thing is great, If I had time, I would put a patent on it, but I have two other patents in the work now and just too many pokers in the fire.

something you may want to think about - I also put a small amount of liquid wax in my mix - leaves a nice shine.
