If your car has a charging port that’s been corroded, there are a few things you can do to clean it. The first step is to remove any corrosion using a mild soap and water. Be sure to use a clean surface - not one that’s been used before. Next, use a wire brush to remove any built-up dirt and dust. Be sure to use a gentle brush - not one that will cause the port to heat up and start corroding again. Finally, use an oven cleaner or other household cleaner to clean the entire charging port area.
