Yes, baking soda does neutralize battery acid.
Baking soda (sodium bicarbonate) is a mild alkaline substance that reacts with the sulfuric acid commonly found in car batteries to neutralize and safely clean up small acid spills or corrosion.
How It Works
- Car battery acid is sulfuric acid, which is highly corrosive
- Baking soda is alkaline and reacts with acid to form a neutral solution of water and salt
- The reaction may bubble or fizz, indicating it’s working
How to Use Baking Soda to Neutralize Battery Acid
For Corroded Terminals:
- Mix 1 tablespoon of baking soda with 1 cup of water
- Dip an old toothbrush or small brush into the solution
- Scrub the battery terminals and cable ends gently
- Rinse with clean water and dry thoroughly
For Small Spills:
- Sprinkle baking soda directly on the spill
- Let it sit until bubbling stops
- Wipe up the residue with a damp cloth
- Dispose of waste safely
Safety Tips
- Wear gloves and eye protection—battery acid is dangerous
- Don’t let baking soda get inside the battery cells—it can neutralize acid inside and reduce battery performance
- Always disconnect the battery before cleaning the terminals
Final Thoughts
Yes, baking soda is an effective and safe way to neutralize battery acid, especially for cleaning corrosion from terminals or managing small spills.
Just be sure to use it correctly, take safety precautions, and follow up with a good rinse and drying to keep your battery clean and functioning properly.
