Why is there white, flaky stuff around my CLS450’s battery post?

The white, flaky stuff that can build up around your CLS450’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 CLS450, 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 CLS450 car battery?

Regularly inspect the terminals and clean them with a mixture of baking soda and water, a wire brush, and a rag.
