The best contact cleaners for many switches and pots contain a
(non-conductive) lubricant that is left behind.... this protects the
contact from rapidly oxidizing and pitting. In the old rotary TV
tuners..... which contains multiple switch wiping contacts, a
lubricating contact cleaner was always used for smooth, reliable, and
long lasting repair.
You obviously DO NOT want to use a CONDUCTIVE grease.... this would
short everything out in a switch or pot.
A light grease is used for smaller low current applications and a
heavier grease is used for higher current applications.
Silicon greases are good but also many petroleum based greases can be
used.
