Cleaning carbon buildup on battery terminals generally involves neutralizing the corrosive substance and safely removing it. Baking soda and water are your best bet for this.
Here's a step-by-step guide:
-
Safety First: Wear safety glasses and gloves to protect yourself from the corrosive material.
-
Prepare the Solution: Mix baking soda and warm water to form a paste or solution. A ratio of approximately 3 parts baking soda to 1 part water works well.
-
Apply the Solution:
- Dip a rag or toothbrush into the baking soda solution.
- Apply the solution to the corroded battery terminals.
- Let it fizz and neutralize the corrosion.
-
Scrub the Terminals: Use an old toothbrush or a terminal cleaning brush to scrub away the loosened corrosion. Apply gentle pressure to avoid damaging the terminals.
-
Rinse and Dry:
- Wipe the terminals with a clean, damp cloth to remove any remaining baking soda residue.
- Thoroughly dry the terminals with a clean cloth.
-
Prevent Future Corrosion: After cleaning, you can apply a thin coat of petroleum jelly (Vaseline) or terminal protectant spray to the terminals to help prevent future corrosion.
Important Considerations:
- Avoid getting the solution inside the battery: Be careful not to let the baking soda solution enter the battery cells, as this can neutralize the sulfuric acid inside and damage the battery. It's best to apply the solution to a rag and then wipe the terminals, rather than pouring or spraying directly.
- Disconnect the Battery (Recommended): For optimal safety, disconnect the battery before cleaning. This minimizes the risk of short circuits. If disconnecting, remember to note the position of the positive (+) and negative (-) terminals.
- Consider a Terminal Cleaning Tool: Specialized terminal cleaning brushes are available that can make the cleaning process easier and more effective.
By following these steps, you can safely and effectively clean carbon buildup from your battery terminals, ensuring good electrical contact and extending the life of your battery.
