I have to agree with the others who recommend frequent hand washing, my new keyboard has changed my hitherto perfectly adequate hand washing habits for the better. The last thing I want to do is accidentally muck up the keyboard with cleaning stuffs and cruft over the years. And beware, ask your (Cough, cough) other user to not smoke in the vicinity of your mac, the smoke will be carried into the innards and settle a gummy deposit that will turn the inside surfaces of your mac into a kind of fly-paper and total magnet for airborne dirt.
