There is nothing as frustrating as waking up early in the morning, ready to go to an important meeting, only for the vehicle to fail to start. Of course, there are various reasons why a car would fail to start, such as a significant part failure. However, it can also be because of corroded battery terminals.

Modern vehicles feature computer-controlled systems, and corrosion on battery terminals can strain it significantly. Cleaning the terminals is the best insurance against such problems.

How to Clean Corroded Battery Terminals

The first thing you need to do is to switch off the vehicle to reduce the chances of grounding the terminals. Then loosen the nut on the negative cable clamp and do the same for the positive. Carefully check for any cracks on the surface of the battery. If you find cracks, you will need to replace the battery. Check for tears on the clamps and cables and replace them if you see large rips.

Pour 1 cup of boiling water in a bowl and mix it with baking soda. The next step is to dip an old toothbrush in the mixture and carefully scrub the corrosion off the terminals. You are free to immerse the battery cables inside the hot water. Keep soaking the toothbrush in hot water as much as possible.

After you are satisfied with the results, rinse the ends with cool water. Wash away all traces of baking soda and corrosion and use a clean cloth to dry the battery. You can use a protection spray or petroleum jelly to lubricate the metallic parts.

Finally, reattach the positive terminal and tighten the nut. Repeat the process for the negative clamp and make sure that it is tight in place.
