What is Corrosion on a Car Battery?
Corrosion happens when the battery acid reacts with metal. This creates a powdery substance on the battery terminals. It can block the flow of electricity.
Corrosion can cause your car to have trouble starting. It also can shorten the battery life. Cleaning corrosion helps your battery work better and last longer.
Why Does Corrosion Form?
Corrosion forms because of these reasons:
- Battery acid leaks from the terminals.
- Battery is old or damaged.
- Terminals are loose or dirty.
- Moisture and heat cause reaction on metal.
When you see corrosion, do not ignore it. Cleaning it soon is very important.

| Old Toothbrush or Wire Brush | Scrub the corrosion gently |
| Baking Soda | Neutralize battery acid |
| Water | Mix with baking soda and rinse |
| Cloth or Paper Towels | Dry the battery after cleaning |
| Petroleum Jelly or Battery Terminal Protector | Prevent future corrosion |
Step-by-Step Guide to Clean Corrosion
Follow these steps carefully. Safety first.
1. Turn Off Your Car
Make sure your car is off. Remove the keys from the ignition.
2. Put On Safety Gloves And Glasses

Use a small amount of clean water to rinse the battery terminals.
Make sure all baking soda and corrosion are washed off.
8. Dry The Battery
Use a clean cloth or paper towels to dry the battery and terminals well.
9. Apply Petroleum Jelly
Put a thin layer of petroleum jelly on the battery terminals.
This helps stop future corrosion.
10. Reconnect The Battery Cables
Attach the positive cable first. Tighten it with a wrench.
Then attach the negative cable. Tighten it too.
11. Close The Hood And Test
Close the car hood. Start the car to check if it runs well.
