Why is there white, flaky stuff around my Silverado 3500 HD’s battery post?

If you notice white, crusty stuff around the battery terminals of your Silverado 3500 HD, 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 Silverado 3500 HD’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I clean corrosion off my Silverado 3500 HD 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 Silverado 3500 HD owner’s manual for instructions on how to do so.
