I never mentioned cleaning WFP... I just turned up and used it, if they asked about it then I explained.
That is a fatal mistake in my experience
I do the same, however i do give a info sheet explaining the process before hand. Many customers are like i dont care what you use so long as its clean, one customer said you can p**s on the windows if you like so long as they are clean when you have finished. Great bloke!
i've one like that , he said "i dont care how you clean them as long as they are clean"
if only all customers were like this .
i take the view that custys need to be made aware of the cleaning method / proccess,
have seen many people say they have been cleaning someones windows for over 12 mths, they are never in , but on one occasion thyey have come back early- to wet windows,
if i were a custy , and did not know about wfp , let alone know how it works, i would be furious.
