Removing Oxidation from Bargman Plug

[angerlo]

Does anyone know how to safely remove oxidation, (presumably cupric-oxide) from the TM Bargman plug? Several days ago we noticed that our brake controller was not connected. We stopped and I used the little file on a nail clipper to remove some of the oxidation. It worked. How can I do a better job of keeping this plug clean without taking it apart?

Start with "Baking soda" or maybe even "coke" the soft drink.

Once clean , a little light grease and or there is a special grease that you could get from an RV parts store.

Let us know.

A little late, I know, but a file or emery board is not really a good solution. I'm under the impression that the copper contacts are plated with a really thin layer of some other metal, and it doesn't take much abrasion to remove the plating. Baking soda or sugar-free (non-sticky) Coke should be good. I use electrical contact cleaner spray, but only because I happen to have some from my old radio restoration days.

Of course, the purpose of the plating is to prevent corrosion, so if you are getting corrosion, it may be macht nichts at this point.

Clean the contacts, squeeze them together for a bit more contact pressure, and add a touch of grease as suggested - just a touch.

Just a thought-maybe its not so much the contact but the actual bargeman connector is not fully seated in the plasctic housing-feel in the rear of the housing and push it in to reseat it.

Don't use regular grease, use dielectric grease for electrical connections.
