White streaks, like milk? Or a little line of spots going down the glass?

defo line of spots down the glass

defo line of spots down the glass
What usually happens is when a drip collects at the top seal, or frame, it gathers dirt, and when heavy enough falls down on the glass. When it dries it leaves behind that dirt in little spots, running down the pane in a little line.
If you clean the frames as well as the glass, do one or two in a row (frame) then come back to the first and just do the glass.
What saves more time is to turn the flow off, tap the brush gently on the glass to remove excess water, and then wipe the crossbar or top frame with the brush of any drips.
If they collect solely on the top seal (often the case with hydrophobic/beading glass) rinse the top of the pane, (turn off the flow; not 100% necessary though) and jam the bristles to the top, collecting the drips, then take care with rinsing the rest of the pane not to rinse that top seal again.
On ground floor it's easier, sometimes I just quickly wipe the top seal or frame with a microfibre to avoid these drips.

its not that im afraid when i go up or down or side to side it leaves streaks on the glazing with air bubbles in from the pole but only happens on some types of glazing.
and it comes from from where the jets are in the brush not the middle or the sides its like there something on the brushes but there isnt.
if theres a small leak in the system could it suck air in i dont use a controller just a tank to pump to vessal to hose battery direct to pump with on off switch.
hope this helps

Funnily enough, i've had a spate of this on several jobs in the last month. Can't remember the last time this has happened so much before. Only 1 or 2 left spots, the rest were ok.
Unless this happens on all your work or windows, then i doubt your technique or kit is to blame.
Until this last month i mostly associated this with 1st cleans when they were done trad before. I suspect if it is not all your work then it is the environment.
Do the jobs or windows have anything in common?
Are any wooden windows?
This time of year many people are out spraying plants etc.
If you think away from what you're doing and what someone else might be doing you will probably find the answer. Then hopefully you can advise so it won't happen in future.

i tell you what it is because i have had the same problem. we have had some quite unsettled windy weather in the last month (dirty air) and before the water is drying dirt is landing in the water
