I know wfp does not cause this problem but it definately shows it up more.
I've had 3 customers say there windows have got worse when I used wfp on them,in fact I could see this quite clearly.
I don't understand why this happens,you would have thought rain would do the same thing,unless its something to do with the pressure from the brush on the window,which is not that great.
This does not effect business at all, but even though I know I haven't caused this its just a bit embarrasing when you know youv'e made it worse.Couple of the windows have gone from a little bit of condensation at the bottom to the virtually the whole window misting up.I went back to the squeegee on one of these windows and it mostly dissappeared except at the bottom.
Anyone know why this happens(the getting worse bit, I know why they' blow' in the first place) or got any views,cheers
