  • What is the white, crusty stuff around my Bonneville’s battery post? The white, flaky stuff that can build up around your Bonneville’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.

If left unaddressed for long enough, it may even cause your battery to prematurely fail.
  • How do I remove corrosion from my Bonneville car battery? Regularly inspecting and cleaning your battery terminals will help keep your Bonneville’s electrical system running smoothly. Before cleaning, reference your owner’s manual for instructions on how to disconnect the battery cables. Once the cables have been disconnected, gently clean the terminals with a mixture of water and baking soda, a wire brush, and a rag.
