houses where you will have no joy with WFP and will be better and quicker usuing trad methods:
wooden windows with poor paintwork/poor putty seal will always have small gaps at top of glass which will be full of dirt and collect your water before dripping down your clean glass leaving horrendous spots/stains.
Windows with aluminium frames will, if the frame gets wet, cause your water to go a milky colour and leave the glass in a terrible condition.
PVC windows with a perished rubber seal around the glass. The rubber will be worn, cracked and have tiny gaps all around full of dirt which again will mix with your water and run down the glass.
PVC windows with filthy frames will need copious amounts of water to wash away all the dirt and rinse thoroughly. Even then, if the windows have not been cleaned where the seals on openers meet the frame, there will be dirt here which will always find its way onto the glass.
You have to account for this thorough cleaning in your price and get up the ladders with the windows open and clean the dirt off the frames under the openers. Then get down and SLUICE the whole frame (windows now closed)
Do this on all the openers and then go back and do all the main panes.
Above all, you will soon accept that there are windows which are a pleasure to clean with WFP and those where you think it has all been a big mistake.
Don`t stress about these windows, just get the trad tools out.
As your work grows, you will be able to lose the bad windows and increase the amount of new work consisting of good WFP windows.
