Shiner is right about first cleans. You DA are too critical of another cleaner whose work you have never even seen.
Firstly the next time you mention this in the pub they won't even remember saying it. Secondly has it occurred to you that you dread going in the pub because you have become the pub bore. All you talk and think about is window cleaning. If they want a bite or a rise out of you all they have to do is dangle a WC carrot.
As soon as you leave they say,'off he goes to tap it all out on his computer....'
And I wear an anarok
If they had told me their windows were spotty then would have told them it's parts of the first clean, but when you have dirty runs all down the window then you cannot blame it on the first clean.
A lot of guys on here are blessed with the good info that comes from everyone from this site. The problem lies with those who have no knowledge about wfp when they buy the equipment there are no instructions saying you have to change the resin when it reaches xxx tds and this is how to clean windows with wfp. Off they go and start cleaning windows and end up with bad results which then gives a bad relfection on wfp.
There are a lot of good wfp suppliers that go all out to help you but some will just fob you off when you ask questions. This was not aimed at the window cleaner but the lack of information you get or wrong information you can get from some suppliers. It's not the case as we all know just move the brush up and down the window and that's it as some have been told.
I have spoken to window cleaners who have bought wfp and then chucked in the garage because of poor results. They are not blessed with the information from this forum as a lot of w/c are not on the net. Hence the information they have received when they bought wfp was not enough for them to get perfect results.
As for the guy if I see him I will let him know what I have been told and help him if he wants as the last thing I would like to see is someone who has invested in wfp start loosing customers.
Cheers, and I'll have a pint on you
