What is the white, crusty stuff around my G6’s battery post?

If you notice white, crusty stuff around the battery terminals of your G6, 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 G6’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I clean corrosion off my G6 vehicle battery?

To help extend the life of your battery, you should routinely inspect and clean the terminals using a baking soda and water mix, wire brush, and rag. Be sure to disconnect the battery cables before cleaning and check your G6 owner’s manual for instructions on how to do so.
