What is the white, crusty stuff around my Thunderbird’s battery post?

A chemical reaction between battery acid and the air can cause a white, crusty buildup to form on the terminals of your Thunderbird car battery. This buildup — known as corrosion — can impede the flow of electricity and cause a range of issues, from poor performance to premature battery failure.

How do I remove corrosion from my Thunderbird car battery?

Regularly inspect the terminals and clean them with a mixture of baking soda and water, a wire brush, and a rag. Disconnect the battery cables before cleaning to help avoid the risk of electrical shock. Always reference and follow the instructions in your vehicle owner’s manual prior to disconnecting the battery cables.
