How do I clean sticky keys?

Apparently, some sweet tea got under the keys of my pretty much brand new MBP. It WAS NOT a spill; it was from the tea-covered hand of my 1 year old son. He laid his hand across the keyboard when both he and the MBP were picked up (after he covered himself in the tea), and apparently that was enough to make some of the keys stick, particularly those on the left side of the keyboard, and most of all the space bar. I find plenty of info on spills, but nothing on how to clean up from just enough liquid to be an annoyance. Like I said, I've only had the laptop for about 3 weeks, so I'm pretty fuming, to say the least. Any help would be greatly appreciated!
