Clean Windows with Pressurewasher?

Was wondering if 1st, anyone will even notice that there is a new post here and 2nd, my mother inlaw lives in a new apartment complex in the city and every year different people with pressurewashers are hired(by strata) to clean all their windows including enclosed decks(as latters are not permitted).She has told us that only once have they actually looked clean when dried.
Noone seems to remember who the guy was that new the secret to clean windows with a pressurewasher. There are places here also that can't be reached with latters would love to offer our services if we could find out what works. And maybe put in for her building also.Would appreciate any and all advice on this,
Thanx Ken and Kathy

You should get an X-Jet Nozzel and use Di water.

Have read so many good things about X-Jet that we have already ordered one, should be here in a few days. Can't wait to try it out.
But could you please explain what Di water is?

Thanx, Kathy

DI water is short for deionized water. The water passes through cylinders that have plastic resins in them and it removes the cations and anions. It is purer than RO water, but the useful life of the cylinders depends on what area you live in, or more particularly the hardness of the water. You can rent the cylinders from most water softening companies.

Scott,

Sorry it took so long to thank-you for the excellent explanation on DI water and also the tip on where to rent the cylinders. Couldn't have asked for a better explanation.

Thanx again, Ken and Kathy
