The white, crusty stuff that can accumulate around W350 car battery terminals is called corrosion.

Corrosion can interfere with the flow of electricity between the battery post and the car's electrical system, sometimes leading to poor electrical performance, difficulty starting, and even premature battery failure.

You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your W350 owner's manual to learn how to disconnect the battery cables.
