Alcohol, microfiber cloth, compressed air can, that's pretty much it. Pop the keys off, you can soak them in water or whatever if you let them dry completely. Put a little bit of alcohol on the cloth and not enough to create drips to clean the screen and outside, be especially cautious around the edges of the screen and any gaps. Clean dust out of the inside by spraying it with the compressed air, keep the can upright and use the plastic tube to aim.
