No, you don't milk it!

I DJ'd a club night on Friday, and some drunk girl spilled her beer on my table, nearly drenching my notebook and empeg. I managed to save them, but my mouse and mouse pad ate it.. The mouse "works" but the buttons are hard to push and seemed gummed up. Anyone have any idea on how to clean this thing without ruining it? It's not a cheap mouse, so I'd like to at least try.
