Why is there white, crusty buildup on my IS300’s battery post?

If you notice white, crusty stuff around the battery terminals of your IS300, 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 IS300’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I remove corrosion from my IS300 car battery?

Regularly inspecting and cleaning your battery terminals will help keep your IS300’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.
