What is the white, crusty substance accumulating on my SLK55 AMG’s battery post?

The white, flaky stuff that can build up around your SLK55 AMG’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 SLK55 AMG, 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 remove corrosion from my SLK55 AMG car battery?

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 SLK55 AMG owner’s manual for instructions on how to do so.
