corrosion on the 9 pin connector

Question

I keep getting enough corrosion on my 9 pin connector that I my blinkers and other lights won't go on. I dutifully clean the plug each time with a baking soda paste, and that fixes the problem. But the corrosion keeps coming back, and I have to do the same thing the next time i go out in the camper, anywhere from a month to 6 months later.

Is there any way to remove that corrosion permanently?

You need to apply some anti- corrosion electrical grease to the pins. You can squirt some into female receptacle then plug in the cord. The grease will transfer to male pins.
Available at most hardware stores in the electrical section.

Once the coating is gone from the metal on the pins they give trouble from then on
Bite the bullet and replace them both
It's not worth chancing a wreck because your signals didn't work or were too dim to see.
Putting grease/lube on the pins is a PREVENTATIVE measure and won't repair the anti corrosion/rust coating that has worn off your pins.
Good Luck, Mike

I have always used basic chassis grease on battery connections, trailer plugs and anything else that is exposed to the weather. Never had a problem yet!

I think it is a buck and some change at the auto parts store.  I use it on all my marine electrical connections.
