When I was driving my taxi around London I got the chance to observe loads of window cleaners both trad and WFP. I could just pull up along side them and pretend to be talking on my phone. I studyed their techniques and learned a lot.
Many wfp cleaners do not clean properly IMO they don't do into the corners and they don't rinse. Thats why you have always have these comments on here and elsewhere about wfp being rubbish.
Its splash and dash heaven. The worst are the employed cleaners on commercial accounts.

Well said.
I have been watching a trad cleaner for months on our estate. He first cleaned off ladders, using his applicator, then squeege, and then ended by polishing the window with another cloth.
He has now changed over to WFP with a hand-pump backpack and a brush. First time round he wet the windows and then squeeged them off with a squeege on a pole.
The last time he just wet the windows with his brush and left them to dry. He only had 3 x 20litre plastic drums of water in his 4x4. We will see how long he will last.
