Corrosion on your car or truck’s battery terminals will cause resistance/restriction in between the battery and the battery cables that lead to important parts of the vehicle like the power control module (PCM), fuse box, or starter, and this can cause problems when trying to start. Your vehicle might not start at all, it might start slowly, or electronics like the headlights might malfunction. This post covers how to clean the battery terminals and other battery parts of corrosion with baking soda and battery terminal cleaner, what to put on the terminals to prevent corrosion, why batteries corrode, and more.
