has for a long time had a large sticker on the front of it explaining about the electricity or something, one of those things that you find stuck on these appliances when you buy them and should take off straight away. Anyway, she didn't, and it's been stuck fast and she now wants to get it off but it's not peeling off cleanly, is leaving lots of 'sticker residue' behind. Anyone know what will bring it off successfully? She used WD40 to get t-shirt transfer off an iron successfully, think it might work with the fridge sticker?
