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

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

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

How do I clean a corroded RX battery terminal?

To help extend the life of your battery, you should routinely inspect and clean the terminals using a baking soda and water mix, wire brush, and rag. Be sure to disconnect the battery cables before cleaning and check your RX owner’s manual for instructions on how to do so.
