Why is there white, flaky stuff around my F-350 Super Duty’s battery post?

If you notice white, crusty stuff around the battery terminals of your F-350 Super Duty, 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 F-350 Super Duty’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I clean corrosion off my F-350 Super Duty vehicle battery?

You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your F-350 Super Duty owner's manual to learn how to disconnect the battery cables. After disconnecting the cables, use a mixture of water and baking soda, a wire brush, and a rag to carefully clean the terminals.
