argh, our local shop didn't have any window cleaner so i bought some finish rinsing agent, the stuff you put in a dishwasher to stop streaks and make glassware sparkly, and watered it down in a spray bottle.
it has made the windows horribly streaky, and they still are even though i'vre gone ovber them twice, one time just using white vinegar.
i assumed it would be pretty much the same stuff as window cleaner, but its made a real mess.
can anyone advise what to do?, i wouldn't care but it's made them so much worse than before i started, which is annoying,..
