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

If you notice white, crusty stuff around the battery terminals of your GR Supra, it's likely corrosion. A chemical reaction between battery acid and the air can create a white, powdery substance that builds up over time on the terminals. This buildup can interfere with the electrical connection between the battery and your GR Supra’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I clean corrosion off my GR Supra vehicle battery?

Regularly inspecting and cleaning your battery terminals will help keep your GR Supra’s electrical system running smoothly. Before cleaning, reference your owner’s manual for instructions on how to disconnect the battery cables.
