Why Does Car Battery Corrosion Happen?

Before discussing how to clean corrosion off car battery, let’s discuss how it happens.

Corrosion around your car battery posts occurs due to sulfuric acid and hydrogen gas vapor escaping from the battery. This vapor sometimes vents out through the top vent blocks, but it can also leak between the posts and where they seal to the plastic casing. 

When this vapor mixes with other gases under the hood, the engine's heat, differences in lead composition, copper from battery wires, and various factors contribute to corrosion.
