Pour a small amount of water on each terminal then use your brush to scrub the corrosion away. Using around a teaspoon of baking soda, or more as necessary, coat your battery terminals and other affected areas.

Inspect the cables to ensure they are free of any fraying, cracks, or anything else that may contribute to a bad connection and have these replaced as needed. If you notice that your battery is swollen, cracked, or bloated, be sure to schedule service right away to have it replaced.
If you notice any other type of buildup, whether it’s from dirt or other grime, this may be causing your trouble as well. While you’re here, it’s important to take a good look at your battery and cables. If the corrosion is extreme enough, you may need to wiggle the connectors loose even after any bolts are loosened. Next, remove the positive cable, which is marked by (+) and is usually red. Always begin with the negative cable first, marked by the (-) sign, and is usually black. Disconnect Your Battery Cablesįirst and foremost, ensure your car is completely off and disconnect your battery cables. Pop your hood and follow these simple steps: 1.
Once you’ve gathered, your materials, you’re ready to begin.

Stiff-bristle brush, wire brush, or professional tool. Here is what you need to clean your battery: This includes wearing the proper rubber gloves and eye protection. This simple process involves battery acid, so you must be taking the proper precautions needed to protect yourself. Now you’ve determined your cause, let’s get to business. Even if you clean it and it begins to work, you should probably have it replaced with a new battery as soon as possible. When batteries get old, corrosion is merely a side effect and not much can be done. Age – If your battery is older than five years, you should accept it's probably on its way out. This depends on the placement of the vents and how much gas escapes through them. If these gases come in contact with your battery’s terminals or car’s cables, corrosion can occur. Gas Escape – In every battery, there are tiny vents the hydrogen gas escapes through. If this occurs, simply clean away the corrosion regularly to ensure reliability. Once this acid touches the terminal, corrosion begins. Overcharged – If the battery is overcharged, the fluid can expand and escape through overflow holes. Some reasons for battery corrosion include: When the likes of salt or moisture are thrown into the equation, the process of corrosion will pick up speed. As the gasses react to the atmosphere in the battery, it begins to produce a corrosive environment leading to battery fluid leakage. The corrosion can be caused by a variety of things due to hydrogen gas being released from the sulfuric acid inside the battery. The power is then thrown into a transient current flow, returning to the battery. The corrosion takes over the battery’s terminal and reduces the connection due to corrosion remaining a terrible conductor of electricity. Typically, the corrosion is white in appearance, one only could describe as “crusty.” It may turn a blue or greenish color when exposed to moisture. What is Battery Corrosion?Ĭorrosion on your car’s battery can be incredibly easy to identify, which is probably why you’re here. Routine cleaning of your terminals will help keep your battery in good health to last longer and perform better – and not leave you stranded with a crusty battery and no connection. While you may assume your battery is done for, it may instead be suffering from a poor connection due to this corrosion around the battery, its terminals, and your car’s cables. Running late due to a car that simply won’t start? And after popping the hood to see what’s going on, you notice something – white crust covering your battery and its terminals.
