Thanks for clearing all that up for me! I have never had a WFP complaint yet due to me cleaning them poorly or them not doing a proper job, so i will just always listen to the majority of my customers, not the fussy ones though obv.
Just thought i would bring it up in topic, because when somebody mentioned that Pure water when used in direct sunlight dries differently, i started to question the whole process as it didn't make sense to me! I know that direct sunlight shows up all marks on the glass looking from the inside, but i was just checking that cleaning with WFP doesn't do a worse job if used in direct sunlight, i'll remember next time, that there are lots of people on here that do complain and can't tell the difference between their brush or squeegee!
