Mac users are supposed to be vain and perhaps this question vindicates that assumption – I'm talking about physically cleaning the machine.
The screen and the silvery surface tends to gather a lot of dust on my Mac; it could also be a function of how "dusty" your environment is – in my case it is quite dusty.
The question is, how should you go about cleaning your Mac? Dry tissue? Wet tissue? Soap? Erasers? (Yes somebody did suggest using an eraser) Why or why not?
