What is corrosion?
Corrosion is battery acid that has seeped from the battery. It forms a greenish-blue crust. Not only is it bad for the battery, but it can be poisonous.
Where does corrosion form?
Usually, corrosion is found on battery terminals due to their conductive abilities.
What are battery terminals?
Battery terminals are usually metal O-ring-like clamps that grab around the battery posts to relay current from the battery to other parts of the car.
How do I clean my terminals?
The best way is with white vinegar on a cotton swab or a bristle. Gloves and eye goggles should be worn. White vinegar is strong enough to remove corrosion but not so strong as to damage your terminals. Removing corrosion in bulk is also OK, but only if the proper safety equipment is being worn!
When removing corrosion, it’s best to disconnect your battery terminals while cleaning. Be sure to write down your radio presets and be ready to set your clock again!
Can corrosion cause permanent damage?
Most likely no, corrosion does not cause anything permanent, but it can cause a need for new battery terminals. It never hurts to have your battery checked from time to time.
