For the ones who say you couldnt work in rain for this reason or that. Have you actually worked in the rain?? Im guessing a good majority havent and the others who may have done and moan at customers complaints, it might be a case of looking at your technique. Stop throwing dummy out at the ones who have invested in this method because of being tired with traditional methods and loosing plenty of days off due to weather. It makes me chuckle the trad workers who work in rain, because that is totally a waste of time and should be turned away. Look into it, before calling me on this point!!
For ones who wfp and it rains after we have cleaned, whos windows are spotted, trad windows or wfp? Provided technique is good on wfp, it certainly wont be wfp windows. Thats also with the rain splashing on the walls etc etc as someone posted earlier. Its like the moaners who say its hard to clean wfp in direct sunlight as it dries with spots, what the heck!! Why dont we dry the water off again? Oh yes, its because its purified and dries clear!!
Its more about how much the operator wants to get wet? However personally, when its hammering itself down and windy, ild sooner take the day off.
