DON'T DO IT!!!
I have ruined 3 keyboards in my life - and 2 of them were the $40 Microsoft Natural Elite split ones, the other a Gateway of my college roommate with volume control buttons, etc.
2 had soda spilled in them, and I immediately ran them under hot water in the tub to get rid of the sticky soda before it had the chance to dry. The third my cat spilled a glass of water on.
All were given a week in the sun by my window to dry, and none ever worked correctly. Some buttons would work, but in all cases something important did not....one it was the space bar, one it was the E key, and one was a whole bunch of keys.
I took it apart and it was a little clear plastic sheet folded onto itself with a circuit board inside of it on another plastic sheet....even washing and drying that thoroughly did nothing to solve the problem.
