Got to do a very big glass sloping roof which has such staining on it. It does come off with a scraper. Is there any wonder stuff i can aplicate on using an extention pole to get it all off before i wfp it?? The frames are old brown metal frames with have left a deposit on the glass. I tried some blitz to no avail, any suggestions would be good. Thanks guys.
