How to Clean Auto Battery Corrosion

Auto battery corrosion can be prevented by coating the metal terminals and contacts in an anti-corrosion product.

Over time, car battery terminals and contacts can become corroded. This happens because the battery terminal and battery contacts are made from different types of metal. Once electricity passes through them, it causes corrosion. Although the problem is common, there are several products manufactured which coat the metals and help prevent corrosion. However, if you have not taken preventive measures, the corrosion can be easily neutralized and cleaned with baking soda.

Things You'll Need

• Baking soda
• Cloth
• Soft-bristled brush
• Petroleum jelly

Instructions

1. Disconnect the battery terminals from the battery. Remove the negative terminal first, followed by the positive terminal.

2. Combine 3 parts baking soda to 1 part water. Stir until the mixture has a paste-like consistency. If the consistency is too thick, add a bit more water; if it's too watery, add more baking soda.

3. Dampen a cloth in water. Squeeze to remove excess water. Dip the cloth in the paste cleaning solution. Scrub the corrosion away from the car battery, contacts and terminals. If needed, a soft-bristled brush, such as an old toothbrush can be used to scrub away hard to remove corrosion.

4. Dampen a clean cloth. Wipe the paste residue from the battery.

5. Reconnect the battery terminals. Dip a cloth in petroleum jelly. Wipe a thin layer of the jelly around the battery terminals and contacts. It helps prevent future corrosion.
