I certainly couldn't have tradded 17 jobs in just over 3 hours, been home for an early lunch and sat on my arse for the last half hour reading this garbage if hadn't changed over to Wfp
I was however a fairly slow meticulous trad window cleaner though, so maybe it it possible it's faster by Terry burrows maybe.
On the flip side of what you've said Jakey, I've had numerous customers ecstatic with the results of wfp cleaning done properly. The tools are only as good as the person using them.
One thing I will admit to, is that the window ledges do start to grey after time with wfp, but the rest of the unit, including the glass comes up much better with a pole
And........ Fight fight fight fight
