Q: How do I clean dirty battery terminals? - Diana
A: Dear Diana,
First disconnect both terminal cables and then apply a baking soda paste that is three parts baking soda and one part water. This will clean corrosion built-up from battery terminals without the need for using a wire brush. The baking soda paste will neutralize corrosion. After reconnecting the clamps to the terminals, wipe them with petroleum jelly to help prevent future corrosion.
