[Amps] tarnish or corrosion?

[Carl]

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.
