Turn the keyboard upside down. That'll get rid of dust etc. I don't really eat much at my keyboard, saitech eclipse 1 I think. I did however blow out a candle twice in a short period of time and each time got wax on my new dell 22 inch, what a plonker rodney! Luckily you can't really see it, only when the screen is blank, like when turned off. Luckily.
