Sticky residue... of the Third Kind.

[chip75]

Don't worry this isn't going to get weird. Just picked up Close Encounters of a Third Kind from Morrisons for £7 (normal amaray case not the cardboard one with the book which was a tenner a few weeks back) but it had one of those stupid white square security stickers on the back, that came of easy enough but I'm having trouble getting the crap it left behind off. Any ideas?

Just to update you guys Morrisons have said anything over £7 gets removed from it's case (unless I imagine it's a big seller like Iron Man 2 which would be counterproductive) for security reasons.
