geoff explained :
What the hell are people bothering cleaning a mbd with soapy water?

Really, just blowing off the worst of the dust is all that's required, the
rest is doing no harm as long as long as you keep fans and heatsinks clean

more is just courting trouble

I was referring to cleaning much more up market electronics than PC's,
especially so before attempting any repairs on said electronics. Most
people would be more than a little wary of dunking electronics in
water, but no harm comes - providing there is nothing which absorbs the
water or where moisture can become trapped.
