I had an old-school keyboard once that I accidentally dumped a large coke right into the top of it. I immediately removed the back cover and washed it all off in the shower. I then dried it the best that I could with a hair dryer and let it set opened-up overnight. The next day I put it back together and it worked like no incident ever occurred. That was my favorite keyboard, and I wasn't about to give it up without a fight.
