Why is there white, crusty buildup on my Sierra 2500 HD’s battery post?

The white, flaky stuff that can build up around your Sierra 2500 HD’s battery terminals is known as corrosion.

If left unaddressed for long enough, it may even cause your battery to prematurely fail.

How do I clean corrosion off my Sierra 2500 HD vehicle 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.
