I just had my first go at removing a rather large price sticker with a hair dryer. It worked a treat - the sticker wouldn't budge at all without the heat, but with it it was relatively easy to peel off. It has however left a bit of a film and you can see where the sticker was. Does anybody know of the best way to get rid of this? Would lighter fluid leave a residue as it's going on to the actual cardboard as opposed to the sticker?
