just had a customer say that the WFP system is leaving a swirly residue on his windows. anyone heard of it? i haven't and wouldn't of thought it possible. I'm going out in the morning to have a look but in the meantime any ideas?

New custy? Long time clean?

"Brush marks" can often be just condensation in between the panes of a damaged sealed unit which shows up this time of year due to air temperature differential on each side of the window.

had about 6 cleans now.

my first thought was a damaged unit but until i see i don't know.

i think he was leds on the back and normal wooden frame DG units on the front

paint oxidising ?  ? ?

Yes, could something your brush is comming into contact with, be 'contaminating' the glass?

And this wouldn't be the office I lost to OCS, though I'm still contracted to clean the insides; which reduced a £100 job down to £40 for me?

I've been opening the windows and smearing vaseline on the exterior of the 1st floor frames, just to mess my competition about.
