I want to make sure the brass prongs in my truck trailer connector are as clean as possible for good electrical connection. Does anyone know a good way to clean them up? Thanks for help.

 

On the 7-Way plug, I loosen the set screw to allow the plug to come out of the recess, use, electronics cleaner, scotch brite pads, or emory cloth to remove corrosion.

 

Thanks BigAlsPSD, that makes sense. I don't know how to do that with my trailer plug on my '04, F250. It doesn't seem to come apart like most plugs. Mine has a connector that plugs into back of plug on truck. The 7 pin receptor is epoxied so moisture can't get to were the wires go. This is kind of had to explain. I tried the electrical cleaner with no luck. In fact, the 4 pin plug next to the 7 pin has bluish crud inside of those 4 pins. I don't know how to clean those too.

 

Sometimes a pipe cleaner works with a cleaner such as DeOxIt ..... Or if you can find a small copper connector. A good electronic store has them.

Thanks. I didn't understand about the "small copper connector". I did Google DeOxIt & called. They suggested the D5 cleaner & the "Shield". I think that's the way I'll go.

 

I forgot a word.. should have been copper connector CLEANER. Kinda like a wire brush only small and round.

 

Some may disagree, but I spray wd-40 into the connector and push the plug in and out5-6 times, letting the contacts rub against each other to clean. It seems to work everytime and last for many months.

 

Thanks r2millers. I don't doubt that would work. Even if it didn't, it would be easy to.remove the WD with a degreaser.

 

If I get some water in there I do the same.

I have wheel bearing grease on mine most of the time.

 

I have always had a small screw to loosen so I can take out the guts then Twice a year I spray contact cleaner in there and at move it around. Use the contact cleaner to try and actually wash it out. I have had green corrosion in there and used battery post cleaner, then instead of water to wash out, I use the contact cleaner. The last time I did this, I then sprayed it down with silicone and it still looks pretty new in there.

Then on the plug itself, This is what I use, see the link:

Then I spray it down with contact cleaner. It drys quickly, then use just a little dielectric grease on the contact prongs.

 

I always carry a set of small standard and phillips, which work great for the set screw on the plug. I take the standard, and scrape the heck outta the brass connectors to clean them up. I transport RV's on the side, and half of them have never been touched in years, so they're all jacked up. Works good enough to get it going down the road.

 

My RV dealer put a bunch of dielectric grease into the trailer plug connector openings. He said you can't use too much of it. I have followed his suggestion for two years and haven't had any issues.
