I’ve been having issues with corrosion on the positive terminal to one of our cars. While I was searching for fixes and preventative tips I came across this tale of woe.

To my horror, the corrosion had returned, turning my replacement clamp into a corroded clamp. When I attempted to loosed the wire attachment bolt on the new/corroded clamp, the whole assembly snapped in half. Horror! Now I had a double battery terminal stump contraption with no clamp - useless for its task of completing the car’s electrical circuit.

I don’t suggest you wait until the problem is as bad as this. Mine was able to be fixed with a basic cleaning kit that you can buy at an auto parts store. From what I’ve found the best way to prevent future corrosion is to use Vaseline. It seals the connection and does not impact connectivity.
