[Amps] Query on oxidation and cado use

[Charles Henry]

A serious question.........1.  I have LOTS of oxidation on my plugs and sockets, even when firmly plugged in and undisturbed.2.  I know how to wipe that off and especially like those few socket designs now used that include a WIPING action when plug is inserted.3.  How to fight this problem short of dissemble and wipe.....    

What about the Cathodic Protection?   Sometimes used to retard degradation of dissimilar metals like rebar inside of concrete?    Is there a way to use this principle on electronics circuits.  Maybe a "gettering" process with everything turned off???    My real question of the week.   Charly
