Why is there white, flaky stuff around my 4Runner’s battery post?

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 clean a corroded 4Runner battery terminal?

Regularly inspecting and cleaning your battery terminals will help keep your 4Runner’s electrical system running smoothly.
