Cleaning High Windows With Pressure Washer

How big is the place that you need 550 gallons or more of pure water to clean with?

3 stories tall and about 400 windows. I know it's most likely not good on the machine but I only try and pull the gun 1/2 way open when I do it and try to be pretty quick with it. Never had any complaints and I always get called to do another job for them.
 
" I go to the auto detailing store and fill up with 550 gallons of spot free water."
SPOT FREE WATER?????? never heard of it. How is it different.
I use a fleet wash product on glass. comes up a treat. I rinse. apply the product with a brush and rinse off.
Truckies won't use anything on their rig's that is going to damage them. Paint or Glass.

Auto detailers use the same water. It's the same water that guys use with the water fed poles here. Or some people call it deionized water also.
 
Sounds like a modified way to wfp those windows. How long would you say it takes to do those windows? Are the windows able to be walked up to from the inside or are they elevated above the 1st floor inside.

I only do the outside windows normally. I would say about 28 hours - 2 14 hour days. I'm pretty good operating a lift so I can move through them at a good pace. I maybe a little slow but I take my time and do a great job as well.

The 1st floor windows I use a small extension pole on from the ground.
 
Can you spray deionized water through a power washer and scrub the windows then rinse wit deionized water again and bang they are done real fast.
 
When cleaning windows you really need to be careful of what I call bounceback. To much pressure and you get a lot of water around the frames of from the siding working it's way back onto the glass and causing issues.
 
Cal Trans 2014,.jpg This is a picture of a building we clean the windows and metal facade with DI clean water. We dont need much pressure so I use a little 12hp at 3000psi cold water machine. Run the hose from the spicket through the DI bottle which then feeds to the pressure washer, which then sprays purified water onto the windows and building. We usually go through 3-4 DI tanks and it takes 8hrs to wash the entire building. THe 3-4 tanks ensures the water stays as close to clean as it can be. The water dries clean on the building and windows as long as the first rinse removes most of the dirt. THe second rinse removes the last bit of dirt/residue and all is good.

Side note- we also use I believe a 24" Unger window scrub bar with a pole to agitate the windows and metal surface on the first rinse. After the agitation 2nd spray removes all the residue. No soap- just DI water and simple scrub.

Franklin  Templeton.jpgFranklin  Templeton 7-7-2012.jpgAnother couple buildings DI water and pressure wash. Wash windows and building facade, use DI water so everything dries nice and clean. Spend maybe 3-4 hours at end of project going over a few spots that water drips from window trim and leaves spotting. All these buildings pictured are 3-5 stories so they don't have davits on the roof for scaffold. The only way, I have figured to clean windows is from a lift and using the DI water. This work is good money and quick once the crew and operators get a few under their belts.

I'd venture to say that 99.9% of the time you will have to use some form of agitation no matter what you're applying. That being the case, since you have to agitate anyway, it would be just as effective to apply regular water, maybe with a little chemical which will rinse easily later with di water. It's not really necessary to do the initial soaking with di water if you're going to scrub anyway.
 
It's not necessary to first rinse with DI water but the most efficient for time. Moving more hoses for each type of water, more labor intensive. Supplying two types of water to the lift workers makes it even more cumbersome and just too many hoses in a confined area. I like to keep it simple and keep on moving, the amount of money saved on labor outways the cost of the treated DI water when using the tanks.
