It's not the "going in" that's really the problem (Score 1)

The worst thing to spill into a computer/keyboard/whatever is vomit. Take whatever substance the user is enjoying... masticate it into tiny bits/pulp, add digestive juices... then dump it back onto the machine. Not only is it wet and bad for the machine... it's a hard time getting a geek willing to do the repair.

I had a machine come in from the athletic department, when I worked in the Uni. repair shop, that I did manage to clean & fix (successfully). I gave up on the keyboard, but got the main box cleaned out (eventually wound up soaking the logic board in a bucket of water [sans battery, etc.]).
