Hi Craig,
Just wanted to say well done on your choice of cleaning method - you will get quicker and more efficient with practice so stick with it.
I've used both methods for a few years now - trad for residential and wfp for commercial and only just let loose on my residential customers in June.
I have had a few complaints and many questions because they don understand the technology of being able to clean a window whilst leaving them wet. After a few days i made up a Company Newsletter and gave one to every customer. It stated how it works and more importantly that for the first few cleans there MAY be signs of spotting etc. It made it clear that ladders were not an option for my Company so they were able to make an informed decision about wether to continue using us. So far I have had only 3 cancellations whilst most people prefere the fact I can see into their bedrooms etc !!!! WONDER WHY.
Low and behold they understood hence the low cancellation rate and fewer complaints and questions.
SAVED ME LOTS OF VALUABLE CLEANING TIME .
Good luck just remember there is a place for both methods, finding which one is right for you will take time - after all if wfp is not for you and your customers dont use it !!!!
Finally, I forsee the real benefit during the autumn/winter time. Damp, mossy floors, slippery roof tiles and loss of work time through bad conditions will be a thing of the past. Of course you could clean now in the rain if you wish (and if your customers are happy for you to do so). All in all wfp will be a really safe option for me as I was never happy climbing a ladder in those conditions anyway.
