What to Do If the Electric Car Charging Port Rusts?

Soak the rusted charging cable plug in white vinegar and wait for five minutes. Then use a brush to scrub off the rust residue on the plug. Wipe it clean with tissue paper. Finally, dry the plug with a hair dryer.

My charging port also rusted before, and this issue needs to be addressed promptly because rust can affect charging efficiency and may even cause short circuits or fires. The main reason is that when the electric car is parked outdoors, rainwater or moisture can seep in, corroding the metal contact points. I would first gently wipe the surface rust with a dry, soft cloth. If the rust is light, I’d apply a solution of white vinegar or baking soda for a few minutes, then rinse it with clean water and let it dry. If the rust is severe, it’s better not to force it to avoid damaging the port—replacing the part or visiting a professional repair shop is safer. Daily protection is essential: make sure the cover is tightly closed after charging, avoid spraying water directly into the charging port when washing the car, and parking in a dry place can significantly reduce the risk of rust. By following these steps, not only will charging remain smooth, but it will also extend the battery’s lifespan.
