What is the white, crusty substance accumulating on my Regal’s battery post?

If you notice white, crusty stuff around the battery terminals of your Regal, it's likely corrosion. A chemical reaction between battery acid and the air can create a white, powdery substance that builds up over time on the terminals. This buildup can interfere with the electrical connection between the battery and your Regal’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I remove corrosion from my Regal car battery?

Regularly inspecting and cleaning your battery terminals will help keep your Regal’s electrical system running smoothly. Before cleaning, reference your owner’s manual for instructions on how to disconnect the battery cables. Once the cables have been disconnected, gently clean the terminals with a mixture of water and baking soda, a wire brush, and a rag.
