I recently spilt some beer on my keyboard and now have about 4 or 5 slightly sticky keys (the bottom left of the keyboard got the worst of it). I immeditately turned the keyboard over and let the beer drip out overnight. I've removed the keys around the area that got the beer and wiped what I could away as best I could then sprayed some screen cleaner on the sticky keys which helped a lot, but the next day the keys are back to being slitghly sticky again...
