What Does Battery Corrosion Look Like?

If you’re experiencing low power inside your vehicle during your Richmond drives, are having trouble starting it, or seeing low voltage codes on your car dashboard, it’s time to check your car battery for corrosion. Allow your engine to cool for at least 30 minutes. Then, open your hood to look at the battery terminals. If the battery terminals have white powdery-looking stuff on them, or they look greenish blue or teal, you have battery corrosion, and you must remove it immediately.

What Causes Car Battery Corrosion?

So, what causes car battery corrosion on your drives around Winchester? Age and time are the biggest culprits. Your battery is continuously heating and cooling as your engine runs, releasing hydrogen gases through its ventilation. These gases mix with surrounding material, creating and depositing a substance at the terminal connection points. 

How to Remove Corrosion From a Car Battery

Anyone that drives a car should know how to clean car battery corrosion. There are two common techniques. The first is purchasing a cleaning solution from an auto parts store specifically for car batteries or creating a DIY solution using everyday household products. Regardless of your choice, use gloves, eye goggles, and a mask when making and handling the solution. Safety should always be your top priority. 

  • Professional car battery cleaner: You can purchase an already-made battery cleaner from any parts center near Danville or order it online. Then, spray the solution on the affected area of the battery terminals. Brush it vigorously with a wire brush to clean it until all of the corrosion is gone.
  • DIY battery cleaner: Remove the connectors from the auto battery terminal, and pour baking soda on the corroded areas to neutralize the battery acids. Add a small amount of water to create a chemical reaction. Dry it with a paper towel. Then brush the corroded surface with a scrub sponge or medium-bristled brush.

Now that you know how to clean car battery corrosion, prevent future decay with an anti-corrosion gel, rust inhibitor spray, or spray battery protector. They are all available at most auto parts stores.
