Cleaning Battery Corrosion

---

Safety First! Before starting, always wear appropriate personal protective equipment (PPE), including gloves (nitrile or rubber are best) and eye protection. Work in a well-ventilated area.

What You'll Need:

• Baking Soda: A mild alkali that neutralizes the acidic corrosion.
• Water: To create a paste or solution with baking soda. Distilled water is preferred.
• Old Toothbrush or Scrub Brush: For scrubbing away the corrosion.
• Clean Rags or Paper Towels: For wiping and drying.
• Petroleum Jelly or Battery Terminal Protectant (Optional): To prevent future corrosion.

Steps:

1. Disconnect the Battery: Always disconnect the battery before cleaning to avoid electrical shock. For car batteries, disconnect the negative (-) terminal first, then the positive (+) terminal.
2. Prepare the Cleaning Solution: Mix baking soda and water to form a paste or solution. A ratio of 3 parts baking soda to 1 part water works well.
3. Apply and Scrub: Apply the baking soda paste or solution to the corroded areas. Use the toothbrush or scrub brush to gently scrub away the corrosion. You'll likely see fizzing as the baking soda neutralizes the acid.
4. Rinse: Rinse the area thoroughly with clean water.
5. Dry: Dry all components completely with clean rags or paper towels.
6. Reassemble: Reconnect the battery terminals, positive (+) first, then negative (-).
7. Protect (Optional): Apply a thin layer of petroleum jelly or battery terminal protectant to the terminals to help prevent future corrosion. This acts as a corrosion inhibitor.

Important Considerations:

• Type of Battery: The cleaning process is generally the same for car batteries, AA, AAA, C, D, and other types of batteries. However, be extra cautious with lithium-ion batteries as they require careful handling. If a lithium-ion battery is severely corroded or damaged, it's best to dispose of it properly and not attempt to clean it.
• Severity of Corrosion: For minor corrosion, a simple baking soda and water solution may be sufficient. For heavy corrosion, you may need to repeat the process or use a specialized battery cleaner.
• Disposal: Dispose of the used baking soda paste and any contaminated materials properly. Contact your local waste management for guidance.
