In the following guide, we will discuss how St. Louis drivers identify car battery corrosion, what causes battery corrosion, how to clean it, and how to prevent it. Luckily, if you maintain and clean it correctly, you can create a fresh surface and spare yourself the cost of a brand new battery.
If you suspect you may have battery corrosion because you’ve experienced diminishing power, issues starting your car, or low voltage codes on your dashboard lights, it’s time to check for corrosion. Pop the hood of your vehicle and inspect the battery terminals and metal. If the terminal has white (sometimes even green/blue/teal), powdery material caked around it— you’ve got corrosion. Also take note of any rust on the metal parts of your terminals and cables.
As mentioned before, time is the main cause of battery corrosion. This is because your car battery is constantly heating and cooling as your motor runs, which releases hydrogen gases through the battery’s ventilation. As these gases are continuously let-off over time, they mix with the surrounding material and form a substance at the connection point. That substance is the corrosion we see, and it occurs at the terminal because that’s where the electric connection is in the case of a car battery.
There are two main ways to remove corrosion from a car battery. You can use solutions from an auto store made specifically for car batteries, or you can do it yourself with household products. It’s important to take safety precautions like wearing gloves, goggles, and a respirator when working around battery acid, electrical currents, and rust.
DIY battery cleaning solution
Now that you’re terminals are clean, prevent further car battery corrosion with rust inhibitor spray, a spray battery protector, or anti-corrosion gel.
