What is the white, crusty stuff around my Grand Marquis’s battery post?

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

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

What do I do about corrosion on my Grand Marquis car battery?

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