Mild??  What, 120 grit?

BE CAREFUL  If the contacts were (possibly ARE if you haven't cleaned them
yet) gold plated you will remove the gold quite easily which will
accelerate the need for contact cleaning (lather, rinse, repeat)  Ending up
with easily corroded, needs-frequent-abrasive-cleaning always cording
contacts.

There are little pre-moistened cleaning packets (towlettes) like those that
come with finger food for cleaning your fingers.  These are called Gold
Wipes or whatever brand name you find, and are a non-abrasive cleaning
solution  pre-moistened cleaning towlette.  This cleaning solution is
expressly formulated for non-destructive cleaning of gold contacts on
electronic equipment.  Would you wipe the dust off of your negatives with a
piece of sand paper???  How about your favorite lense?

OK now to climb down off of this soap box and into some Kevlar and Nomex
underware.
