What is the white, crusty substance accumulating on my E550’s battery post?

If you notice white, crusty stuff around the battery terminals of your E550, it's likely corrosion.

This buildup can interfere with the electrical connection between the battery and your E550’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I remove corrosion from my E550 car battery?

Regularly inspecting and cleaning your battery terminals will help keep your E550’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.
