Hi thanks for the reply. I was just curious. I think sometimes we are all too fussy. I was talking to a customer the other day, She said to me that she loves wfp because it cleans her upvc frames and to her that is far more important than the odd spot on her windows, which she said she had never noticed anyway.
NORMAL people seem to be firstly seeking reliability, then decent job not perfect but decent, then price last. Well that is what I think. I do work in an affluent suburb so maybe different in other places.
I have been rinsing on for last 6 weeks or so and haven't had a complaint. Have even been asking selected customers to let me know if there is problem, as I have a new brush etc, but none have, even when I have quizzed them on the next visit.
BUT when I do half the front of a house rinsing off and the other half rinse on I CAN tell the difference, but only with a very good look and I am sure normal custys don't inspect them to that degree.
