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

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

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

How do I clean corrosion off my Roadmaster vehicle battery?

You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals.
