If you live in Austin and aren’t sure how to remove corrosion from a car battery, Aston Martin Austin can help. Read on to learn how to identify car battery corrosion, what causes battery corrosion, how to remove corrosion from a battery, and how to prevent it in the future. The good news is that once your battery is properly cleaned and maintained, it should last you much longer.

What Does Battery Corrosion Look Like?

Have you been experiencing weaker power, difficulty starting your car, or low voltage codes displayed on the dashboard while driving around San Antonio? If so, it’s time to do a visual check for battery corrosion. When your vehicle’s engine is fully cooled and hasn’t been used for at least 30 minutes, pop the hood so you can inspect your battery terminals. If the terminals are caked in white powdery substance, or if it appears green, blue, or teal, you’re dealing with battery corrosion. 

What Causes Car Battery Corrosion?

If you’re wondering what causes car battery corrosion, age is the main culprit. Your vehicle’s battery is continually heating and cooling as the engine runs, releasing hydrogen gases through ventilation. As these gases are continually dispersed over time, they mix with surrounding material and create a substance at the connection point. That substance is battery corrosion, and it occurs at the terminal because that’s where the electrical connection is in a car battery.

How to Clean Car Battery Corrosion

Want to know how to remove corrosion from a car battery? There are two main ways to remove battery corrosion. You could buy a dedicated cleaner solution from an auto parts store around Dallas which is made specifically for vehicle batteries, or you could make a solution yourself using common household products. Either way, use gloves, goggles, and a respirator or mask when handling the solution or creating your own. Safety should always be your top priority.

If using a professional battery cleaner:

  • Spray it liberally on the affected surface of the battery, then brush it with a wire brush until all of the corrosion is removed.

How to make a DIY battery cleaning solution:

  • First, remove the connectors from the battery terminal. Then, pour baking soda on the corrosion to neutralize the acids. Then, add some water to create a chemical reaction. Dry it with a paper towel, then brush the affected area with a scrub sponge or brush.

Once you remove the corrosion from your vehicle’s battery terminals, you can prevent future corrosion by using a rust inhibitor spray, a spray-on battery protector, or an anti-corrosion gel.
