Newbie residential cleaner

Hey guys… thanks in advance to help me out in my personal cleaning experience…

I bought a Karcher pressure washer to clean my house windows (1st & 2nd storey windows)… I followed the steps as per the following link: LINK REMOVED FOR SECURITY

Tried various soap mixture.

However, everytime i left the windows to dry by itself, there are watermarks (spots) formed. I read that it is some form of mineral built up from hard water?

Is there any method to not allow these watermarks forming without wiping with squeegee?

The whole reason of me getting the pressure washer was because I do not want to climb up to level 2 anymore.

I’m thinking maybe this topic have been discussed before, but I just can’t seem to locate it. And i’m frustrated at my window. =(

You are not going to get your windows drying clean with a pressure washer and normal water i'm afraid. 

You need purified water and you need to use a water fed pole system if you don't want to climb. A pressure washer is just going to blow dirt all over the place and glass.

You need purified water with either di vessels and resin or an r/o system. Normal tap water will leave so many water Marks and windows shouldn't be cleaned that way. Theres so many you tube videos around now to guide you through the process. Jet washing windows with normal tap water is a recipe for disaster 

Your more then likely now going have to get up thr ladders to remove the hard water spots 

Hey folks.. thank you so much for the heads up.. I'll read up on purified water..

I was feeding water from the tap.. I thought adding detergent in the mix would solve the issue..

As I have already bought the pressure washer.. any further advise is welcome.. mine has 2 inlet.. 1 for water and the other for detergent/soap..
