I've just about finished a new renovation to my home. While the renovation was proceeding a large X with electrical insulating tape was placed on a sliding door - to stop people waking into it.
Cleanup time is just around the corner and I'm wondering how do I get rid of the glue residue left on the door
I've tried ordinary window cleaner but that hasn't made any difference. I know I can use the likes of a Stanley blade, but I don't want to just in case of scratches
Any suggestions
