WFP question

35’ Flip Lock Carbon Fiber Telescopic Pole
6 X 6 Carbon Fiber sections with a 16" nylon brush. 6.0 lbs. By Pulex

My last post was in regards to feeling like I made a mistake with the DI cart and WFP… The above is the Pole and brush I have… Is this a bad way to learn because of the sheer size? I bout the unit lightly used and saved a ton of money ( system only had 700 gallons run through it )

I just today attempted a 3 story commercial building 60% of the building looks good but the other do not. In fact they looked better when they were dirty… no matter how I rinse, Rinse rinse I am still finding spots and on a few windows there seems to be a HAZE left behind… It seems like it takes for ever to dry and when it does I have spots along bottom and a few sides. I currently in the unit I bought have PENCIL type spray that come through the brush… Should I cheange these to fans? and where to I buy if need be… I almost feel like this brush that is listed above is not right???

I tested the water befor with TDS meter and it was at 204 then I started system and it went down to 0 ( this is good correct?)

Another question I have is this, Does anyone know of anyone near DAYTON OHIO that would be will to train me… I want this to work but right now I am pretty discouraged.

Sorry to ramble just looking for HELP.

White or translucent spots on the sides and bottom are due to not rinsing enough.

The haze is soap. After that window dries, go back and do it again. This time, without hitting the top frame. Just come about an inch from the top of the glass with the brush and don’t get water on the frame.
