Hey up chaps. The window cleaners enemy that is window installers v often leave those bloody stickers on the windows. Or like today, where they took the sticker off, but all the glue stayed on. What's your removal tips?
Usually I just use a scraper blade whilst keeping a wfp stream running over it. That works ok but it can take a lot of scraping and can be hard to tell you've got it all off until the window dries.
Any chemical or anything to make it easier? I know there seems to be a variety of glues used for these stickers.
