What is the white, crusty stuff around my ProMaster 3500’s battery post?

The white, flaky stuff that can build up around your ProMaster 3500’s battery terminals is known as corrosion.

Corrosion can affect the flow of electricity between your battery and the electrical system in your ProMaster 3500, possibly causing issues with electrical performance and starting. If left unaddressed for long enough, it may even cause your battery to prematurely fail.

How do I clean a corroded ProMaster 3500 battery terminal?

To help extend the life of your battery, you should routinely inspect and clean the terminals using a baking soda and water mix, wire brush, and rag. Be sure to disconnect the battery cables before cleaning and check your ProMaster 3500 owner’s manual for instructions on how to do so.
