Pencil erasers.  Good.  If you can still buy the rougher ink erasers that
come in a pencil form - they work great!  Sand paper only if you don't have
any plating (commonly tin/nickel).  Anyone who uses sandpaper on gold
plating/flash needs to get yelled at.  :-)

Stan's probably right.  But I'm not sure I understand what would upset the
dash electrics except possibly a poor ground.  Or a high voltage spike
coupling into the harness.
