I have spilled my bong into the keyboard, five times (I then gave up on smoking the bong and went back to a pipe for this reason). It's a $80 keyboard, and I haven't been able to find a cheaper replacement that doesn't hurt my wrists. This one is perfect - except that it's not spill proof. I got really good at taking that keyboard apart.... Have permanently trashed one of them (might be able to revive it by taking it totally apart and individually scrubbing every contact), and the other one has been patched up and is working right now. First you take the case off, which is like a million screws of two different types. Then the key overlays for the special function keys kinda fall off (also, they don't go back on cleanly). Unplug the little cables going to the switch membranes (carefully, they can snap or fatigue). Then you take a razor blade and cut off the molded plastic tabs holding the key-retaining plastic frame onto the metal backing plate. Flex it and the keys will fall off. Now you can peel the three switch membranes apart, and put papertowels between them to dry them. Then you put it back together. Note that the keys won't stay on the key retaining plate until you replace the molded plastic tabs (using epoxy putty - which is unfortunately harder to take off than the original when you have to go back and do it again), which takes 30 minutes to really harden. But once that's in, it's hard to put a key back on without breaking it. So putting it together is a matter of alternating tweezer-finger key placement, then jig it up with clamps, epoxy, wait, repeat. Oh, and you're doing this half-way high, because you were smoking the bong when you spilled it. It's a real buzz kill, for sure.... And then you realize you can't find the damned screws and spend half an hr on your hands and knees searching for the screws.
I've also had my share of sneezed-away lines, too, but never of anything terribly scarce or valuable.
