Key Servicing: Nokia Candybar?

Seems like the problem with the keys on 2 of my Nokia candy bar phones is some
sort of black-ish gunk on the silver-colored surface that touches the gold spots
on the circuit board when keys are pressed.

I've had some success with a Q-tip and a little fine-weight automotive polishing
compound.

Anybody got something better/less destructive?
