I extend the cleaning I do on any computer component to a
quick run-over with esopropyl-alcohol (don't know if it has a
proper english translation). Works nicely (on metal that
is, better not use it on plastic, since it's potent stuff).
Excellent to clean connetors etc. Elsewhere, I just huff off
the biggest heaps of dust... ;-)
Haven't seen Mr Sheen anywhere around here.
