[quote name='Mr Unoriginal']Well I put some alcohol on a q-tip and rubbed it around the button. It seemed to work pretty well, it still sticks a bit, so I may try one more time.
Interestingly enough, Nintendo tells you to get a toothbrush wet and rub the bristles in and around the buttons. That to me seems more dangerous than a little alcohol.[/QUOTE]
Combine the two. Rubbing alcohol is the main ingredient in commercial electronics cleaners (just take a whiff to confirm). A tooth brush will be stiff enough to clear out some debris but not stiff enough to scratch any leads or contacts.
Like the others say, just turn the devilce upside down for a few hours or maybe a day to be certain its dried out on the inside, although alcohol evaporates much faster than water.
