In France we have alcool ménager (household alcohol) that is used as a general purpose cleaner/degreaser.[br] Worked perfectly on the rubber parts of an old Microsoft webcam. Just wiped it with a few drops on a paper kitchen towel. The stickiness was only superficial and there was hard rubber underneath. My guess is that any alcohol would do - gin, vodka, anything you have to hand.
