I have build up of crud on my truck / trailer plug. If I clean it with contact cleaner and a little emery cloth… can I simply apply a small amount general purpose grease to it? Or do I need a special electrical grease for some reason?
Electrical contact grease would be your best bet, autozone or similar store will have it.
Costs about a buck at the checkout counter of the auto parts store. Dielectric grease.
Thanks…..
Be sure you have a cover for your plugs, otherwise that grease will just attract more dirt and road gunk.
I hate these plugs so much. Mine just hangs down by the hitch and I have found that using the runber cover just seems to make it corrode even more because it inevitably gets wet. Grease seemed to make things worse too. Had the best luck just leaving it open and planning on using qtips when needed. Finally wised up and just bought a 4 plug converter for the round 7 way.
