Cleaning Electrical Connectors
I would like to remove all the tarnish and corrosion on the electrical connectors in my car. What's the best way to clean electrical connectors? I would like to do it chemically if possible. All the wiring harnesses are out of the car.
Beware that some electrical contact cleaners will melt some plastics. I would disassemble the connector, a small blade is used to remove the metal terminal from the plastic connector, and then clean with cleaner and a small wire brush, coat with Kopper-Shield or dielectric grease and reassemble. A little time consuming but it will last much longer and lessen the chance of reoccuring.---------
Dipped my entire connectors in metal prep from ppg. Look like new when done. DFidnt hurt the plastic either.
