Cyber Clean. That gooey yellow reusable cleaning compound. http://www.cyberclean.ch/ Claimed - suitable for cleaning all electronic products and leaves no residue or odor. But I used it on my iPod touch and it was coated with residue. Comes off when I wipe it with a wet cloth though. Was wondering if anyone else has used it and had that problem? My iPod's got a BSE skin on it, but it shouldn't be reacting with the skin.
