I used my trolley and pole for first time. I was told to brush the top of windows first then the rest then clean the top again so that it drips down and rinses any stains below, right? After I finished practising on my girlfriend's house it was cleaner than before, but there were some stubborn stains which I couldn't get rid of. What's the general technique for wfp? Windows on the first floor- the stains can't be seen, so how do you know if you're missing a difficult stain? To get these off do you need to put a scrapper on pole?
The window in the picture was difficult to reach, so I just climbed a window and put my new ionic's Grafter (which bent a fair bit on it) It was pretty much horizontal. Is this how you would reach this window?
