Washing windows with a pressure washer can work. You will need to do some of the folowing things, to make it work.
1. You will need to brush or scrub them in some way. Soap alone will probably not do it, unless they are washed VERY frequently.
2. You will need to use either DI or RO water for rinse. DI is a higher quality water, and a little more expensive. There are places that ship to Tucson from Phoenix, but, the water places are always leery of renting their tanks to Pressure washing contractors, because so many go out of business so quickly, and the tanks disappear.
3. A rinse aid, in Arizona, will not work. Our water is way too hard for any rinse aid, for the clarity that you will need, or want.

I am not sure about the ro but the DI tanks work great they leave it absolutley spotless. We use it for the car dealerships and as long as they are the new cars and are not driven much you just spray them off but if they are used then you need to wash them before you rinse to get the look you are wanting. I guess this would be the same for the windows If they have not been washed in a while you should be able to wash with a brush and soap then rinse with the DI

You want to brush it, preferably with Joy dishwashing soap. Then you can rinse it. I guess I should have been more clear.

Most of the time you don't even need soap. We just brush with DI water and rinse with DI water using a waterfed pole.
Three ways to do it.
DI - Run water through a cylindrical tank. DI beads in the tank attract the minerals in the water so they are not left on the glass. Problem is the beads get covered with minerals so you must get them recharged, this can get expensive. The harder the water, the faster they need recharging. Benefit is that it is very simple and initial set up is cost effective.
RO - Reverse Osmosis. Filter most of the minerals out of the water. Problem is that it is slow and much more complicated so you need a bigger more expensive system with batteries, pumps and buffer tank. Benefit is tanks don't need to be recharged so water is cheaper in the long run.
RODI - Reverse osmosis system filters out 95% of the minerals and then goes through a small DI tank to get the last little bit. This is the best system because the water is cheap and it is 100% spot free.

I use RO without the Di system and have never had a problem with spotting unless the membranes get bad. Either way can be effective just depending upon how much you will need. My RO makes roughly 1500 gallons per day if needed and with a 2" water pump transfering water is really fast.

Once you see the guys washing windows with the waterfed poles, you will want to spend the money and get one, they are great.
My friend has a 60' superlight carbon fiber pole that weighs around 7 pounds and is easy to use.
The equipment will cost you some money but you can knockout windows fast and leave them spot-free so you can go on to other windows and make more money per day.

There are benefits to DI that RO alone can't give. The DI resin imparts an electrical charge that is the opposite of the dirt on the windows. So beyond getting 000 TDS from the DI you get that extra pull from the electrical charge which give a longer lasting clean. Of course for maintenance work that might not be a big deal. For residential guys it's very important.
