I'd recommend using a nonabrasive cleaner rather than a pencil eraser.
I've heard some stories, over the years, about adverse effects from
bits of the rubber and abrasive floatig around in equipment chassis.

When I had a poor-contact problem with a Ten-Tec Scout I'd purchased,
I was advised to clean the board-edge connectors and sockets for the
plug-in band modules. I scrubbed 'em down with DeOxIt and some Q-tips
and paper towels, put the 40-meter module back in, and it worked
perfectly and continues to do so until today.

Dried-out electrolytic capacitors can be another problem with older
gear, especially glassFET models which tend to run hot.
