Having JUST replaced our keyboard (thanks to a kitten and milk disaster), I put a sheet of the self-sealing saran wrap over the keyboard. It stretches enough to allow the keys to be pressed, and does a marvelous job at keeping the crud out of the keyboard!

Oh, nice! This is an awesome idea, I have ruined too many keyboards, and I hate dust! I do have that plastic wrap too, and am going to do this! Thank you!
