What is the white, crusty stuff around my Q45’s battery post?

The white, crusty stuff that can accumulate around Q45 car battery terminals is called corrosion. It is caused by a chemical reaction between the battery acid and the air, which creates a white, powdery substance that can build up on the terminals over time. 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.

How do I remove corrosion from my Q45 car battery?

Regularly inspecting and cleaning your battery terminals will help keep your Q45’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.
