How to clean trailer plug terminals???

I kinda need help quick, so the other weekend I hooked up to my buddys landscaping trailer, everything was fine until I plugged in the harness, No Lights...no big deal cuz it wasnt much of a drive, but I gotta haul a boat tomrrow a little ways and Id like to be legal lol.

I need some suggestions on cleaning my trailer plugs. What is the best way to clean the terminals on the small 4 prong? The big plug is fine, just a little dirt inside the cover, but im still going to clean the contacts and put di-electric grease on them.

Thanks in advance.

My advice is to forget trying to use the 4 prong and get an adaptor for the big one. Much easier to keep the big on reliable based on my own experience. The big one also latches in better.

Senix: did you use any kind of solvent?

btw: thats a big *****ing camper!

I think I might have a small wire brush, maybe even a .22 brass cleaning brush would work, and possibly some electric cleaner.

You need something that will clean the copper corrosion. I use bar keepers friend cleaner. Another thing that works well is jewlery cleaner.

You can buy spray cans of electrical contact cleaner which may help. I'd prefer getting in there with a brush or narrow abrasive to get it clean, then dielectric grease to keep it from corroding again. Good luck.

If you use muratic acid the plug will be gone tomorrow

A small wire brush works GREAT. Then spray with contact cleaner

A brush that fits those small openings has been available at many RV dealerships for years and maybe some automotive stores. Not sure about the automotive stores. Not much demand for it, so it many be hard to find. I have one on my truck, but seldom use it. If an RV dealer doesn't have it, they can easily get you one as they are in the catalogs.
