Read on to learn what car battery corrosion looks like, what causes car battery corrosion, and how to remove corrosion from a car battery. Once your battery is correctly cleaned and properly maintained, it should last you much longer.

What Does Battery Corrosion Look Like?

Are you experiencing weaker power inside your vehicle, trouble starting your car, or maybe you’re seeing low voltage codes displayed on your dashboard on those drives to East Baton Rouge? If so, you should check your battery for corrosion. When your car’s engine is fully cooled and has been off for at least 30 minutes, open the hood so you can look at your battery terminals. If the battery terminals are covered in white powdery material or look green, blue, or teal, you have battery corrosion.

What Causes Car Battery Corrosion?

If you’re curious about what causes car battery corrosion, age is the main cause. Your car’s battery is constantly heating and cooling while the engine runs which then releases hydrogen gases through ventilation. These gases are continually dispersed and as they mix with surrounding material they create a substance at the connection point or terminals. That is what causes battery corrosion.

How to Remove Corrosion From a Car Battery

Now you probably want to know how to remove corrosion from a car battery. There are two key methods to remove car battery corrosion. The first method is to buy a cleaning solution from an auto parts store around Ascension that is made specifically for auto batteries, or you could make a DIY solution yourself using common household products. Regardless of which method you choose, use gloves, eye goggles, and a respirator or mask when handling the solution or creating your own. Safety is paramount.

  • Professional battery cleaner: Spray the solution liberally on the affected area of the battery, then brush it with a wire brush until all of the battery corrosion is removed.
  • DIY battery cleaner: First, remove the connectors from the battery terminal. Then, pour baking soda on the corrosion areas to neutralize the acids. Next, add a little water to create a chemical reaction. Dry it with a paper towel, then brush the affected surface with a scrub sponge or brush.

Now that you know how to remove corrosion from a car battery’s terminals, you can prevent future corrosion by using a rust inhibitor spray, a spray battery protector, or an anti-corrosion gel available at the auto parts department at Acura of Baton Rouge. You can order parts and accessories online or call the parts center to talk to one of our parts specialists.
