SE NH is likely as humid as FL what with all the salt water fog and coastal
storms plus all the road salt.
That is what they make DeOxit for.
I use the D-100 version on automotive and yard equipment connectors and
havent had a problem in years.
Apply sparingly, that means a small drop, plug/unplug several times to break
the oxidation, and go on your merry way.

Have you ever thought of putting petroleum jelly on the contacts to
prevent the moist air from getting to the metal? Worth a try!

Quoting Charles Harpole <hs0zcw@gmail.com>:
I have a hot and humid year round weather. I have lots of problems with
some kind of material that gets on exposed plugs and sockets that
interferes with electric conduction.
That is, plugs normally kept in their sockets stop conducting.
The small plug/sockets between boards inside the Alpha 87a are a real
example--as is my use of Cinch Jones plugs/sockets on a patch panel for
rotors. Other plugs too, same problem.
These plugs use metal and somehow they lose good conduction either in
constant "plugged in" state or "in and out."
Because these type of plugs have a "wiping action," I can fix the problem
by plugging in several times. Then they conduct fine.
Question: There is no sign of real corrosion and no pitting nor change
in
the metal, so what is cause of this problem?
The metal looks ok or perhaps tarnished. What is tarnish and how is it
different from corrosion? Web is vague.
Tnx 73, Charly
