Battery corrosion is a common issue that affects vehicles, particularly during monsoon seasons when humidity levels rise. The whitish-green or blue powdery substance that forms on battery terminals can cause starting problems and reduce your battery's lifespan.
Learning how to remove battery corrosion is an essential maintenance skill that can save you from unexpected breakdowns during long journeys. This guide provides simple, effective tips on how do you get rid of battery corrosion without professional help.
How to remove car battery corrosion easily
Before starting the process, wear protective gloves and eyewear. Follow these steps to remove car battery corrosion effectively:
1. Disconnect the battery
Turn off the engine and remove the negative terminal (usually black, marked with a ‘-’) first, then the positive terminal (typically red, marked with a ‘+’).
2. Prepare a cleaning solution
A paste made from baking soda and water effectively neutralises acidic corrosion.
3. Clean the terminals
Use a wire brush or an old toothbrush to apply the paste onto the corroded areas. Scrub gently but thoroughly until all corrosion is removed.
For severe cases, commercial-grade battery cleaners can be more effective.
4. Rinse and dry
Rinse the battery terminals with clean water to remove any residue. Make sure the mixture doesn’t enter the battery vents and casing. Use a cotton cloth to dry the terminals completely.
5. Apply petroleum jelly
Protect the terminals from future buildup by coating them with a layer of petroleum jelly or dielectric grease.
6. Reconnect terminals
Attach the positive terminal first, then the negative and ensure they are securely fastened before restarting the engine.
Conclusion
Corrosion is often a sign of battery ageing, overcharging, overfilling with water or underlying electrical system issues—problems that should not be ignored. Now that you know how to get rid of battery acid corrosion, you can extend your battery’s lifespan and avoid costly repairs. To keep your car in top condition, schedule regular servicing and maintenance.
