To be honest, I'm surprised at how uninterested most people are these days when I tell them how I'm going to clean their windows.
Most just want them cleaned, without a long boring technical explanation from some bloke who they just asked to clean their windows!
Yeah I found that too.
When I first went over to wfp, I was dying for a custie to ask how it all worked!
I wanted to get the tds meter out and compare their water etc, and show the difference. But no one asked, so when I tried to force an explanation onto them

they didn't seem that interested.
Now of course it's not so exciting

and I find it's best to just get on with it, and don't give them anything to worry about. If I say anything, it's just that I find it a bit safer than working from ladders all day, and that I can now reach those awkward windows!
Although one yesterday, I just mentioned that I'd be cleaning them differently, and she said 'Oh, no, I want all the ledges cleaned too'
I replied that this system is as good, and will do the sills. She just said "Well I don't know how!"
Just let me get on with them and you'll see!
