My rent-a-geek friend usually recommends to his clients that electronics that have been exposed to water be left alone for about a week before trying to turn them on or recharging the battery. Of all the spilled-upon electronics he's dealt with, beer usually does the worst damage. I would have thought that something sticky like soda pop would be worse.

I usually have a cup of tea while I am reading, but I am very careful to keep it away from my ebook reader and audiobook player.
