When DD was small, extremely overprotective DH stuck paper with double-sided tape over the small panels of old glass on a glass-fronted bookcase, in case she should fall through. She never came anywhere near it. Now 6 years later, I would like to get the horrible sticky remnants of the glue off the glass panes. I have tried WD40, windolene, oil, scraping with a razor blade, warming with a warm wet cloth ... all ideas from google. Has anyone, ever, managed to get this stuff off???????
