Keyboards are pretty resilient. We had an office party once and someone spilled champagne all over a couple of the keyboards. We took them to the bathroom, rinsed them off and put them under the hand dryers. Good as new!

I've spilled all sorts of things on mine!

If you are clumsy like me, get one of those plastic covers that fits over the keyboard...sometimes it doesn't fit very well, but it does keep liquid stuff from getting into the keyboard.
