I got a WFP cleaner to do my windows, they have not been cleaned for years :Image1: , unfortunately they still have quite a lot of that murky look about them, not clear at all. Is it best to clean the windows with a cloth first time before you start using the WFP, just for the first time to get that hard to remove murk, even rubbing it with a cloth it needed a bit of elbow grease to shift it.
Any opinions?
