Understanding Battery Corrosion
The Chemistry of Corrosion
Battery corrosion is a common problem that can occur in car batteries. It happens when the battery’s electrolyte solution, which is typically a mixture of sulfuric acid and water, leaks out and comes into contact with the battery terminals. This contact can cause a chemical reaction that results in the formation of white, powdery substance on the terminals, known as corrosion.
The corrosive substance is primarily composed of lead sulfate, which is a byproduct of the battery’s chemical reaction. This build-up can interfere with the electrical connection between the battery and the car’s electrical system, leading to a variety of problems, such as a slow crank, dim headlights, or even complete engine failure.
Identifying Battery Corrosion
Corrosion often appears as a white, powdery substance on the battery terminals and surrounding areas. It may also have a bluish or greenish tinge in some cases. Here are some signs that your car battery might be corroded:
- Slow engine cranking
- Dim headlights
- Clicking sound when trying to start the engine
- Warning lights on the dashboard
- Battery terminals appear white, powdery, or discolored
The Importance of Addressing Corrosion
Ignoring battery corrosion can lead to more serious problems. The build-up can eventually cause the battery terminals to become disconnected entirely, preventing the car from starting. Corrosion can also damage the battery itself, shortening its lifespan and potentially leading to a complete battery failure.
Tools and Safety Precautions
Essential Tools
Before attempting to remove battery corrosion, gather the following tools:
- Rubber gloves
- Safety glasses
- Baking soda
- Water
- Old toothbrush or wire brush
- Terminal cleaner
- Rag or paper towels
- Battery terminal protector (optional)
Safety First
Always exercise caution when working with car batteries. Batteries contain sulfuric acid, which is highly corrosive. Never work on a battery without wearing rubber gloves and safety glasses to protect your skin and eyes from contact with the acid.
Make sure to disconnect the negative terminal first when working on a battery. This will prevent accidental short circuits. Never attempt to jump-start a battery with corrosion on the terminals. Corrosion can cause sparks and potentially ignite the battery.

Removing Corrosion from the Battery Terminals
Now that you have the necessary tools and materials, let’s move on to the removal process:
Disconnect the battery: Before you start cleaning the terminals, make sure to disconnect the battery to prevent any accidental short circuits. Locate the negative (black) cable and loosen the nut on the terminal clamp. Then, pull the cable off the terminal.
Mix baking soda and water: In a small bowl, mix 1 tablespoon of baking soda with 2 tablespoons of water to form a paste.
Apply the paste: Use a wire brush to apply the paste to the corroded terminals. Make sure to cover the entire area, but avoid getting the paste on any surrounding surfaces.
Let it sit: Allow the paste to sit on the terminals for about 10-15 minutes. This will give the baking soda time to break down the corrosion.
Scrub the terminals: Use a wire brush to scrub the terminals, working from the center outwards. Be gentle, as the terminals can be easily damaged.
Rinse with water: Use a damp cloth to wipe away the paste and corrosion. Make sure to remove any remaining residue.
Use a terminal cleaning brush: Use a terminal cleaning brush to remove any remaining corrosion or residue from the terminals.
Reconnect the battery: Once the terminals are clean, reconnect the negative (black) cable to the terminal. Make sure it’s securely fastened.
Preventing Corrosion from Coming Back
To prevent corrosion from coming back, follow these tips:
Apply a terminal protector: You can purchase a terminal protector or use a thin layer of petroleum jelly to protect the terminals from moisture.
Keep the battery terminals clean: Regularly clean the terminals to prevent corrosion from building up.
