Why is there white, crusty buildup on my Fiero’s battery post?

The white, flaky stuff that can build up around your Fiero’s battery terminals is known as corrosion. Acid leaking from your vehicle’s battery post can have a chemical reaction with the air, leading to an accumulation of the white, powdery substance over time. Corrosion can affect the flow of electricity between your battery and the electrical system in your Fiero, possibly causing issues with electrical performance and starting. If left unaddressed for long enough, it may even cause your battery to prematurely fail.

What do I do about corrosion on my Fiero car battery?

You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your Fiero 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.
