Battery corrosion can occur when the acid inside a battery leaks or reacts with the metal terminals, resulting in a white or bluish-green powdery substance. It’s important to clean battery corrosion promptly to prevent damage to the electronic device or the battery itself. Here’s a step-by-step guide on how to clean battery corrosion:

Materials you’ll need:

  1. Baking soda
  2. Water
  3. Disposable gloves
  4. Old toothbrush or a small brush
  5. Cotton swabs
  6. Vinegar (optional)
  7. Paper towels or a clean cloth

 

Steps:

  1. Safety first:
    • Put on disposable gloves to protect your hands from any residue or chemicals.
  2. Remove the battery:
    • If possible, remove the battery from the device to prevent further damage.
  3. Inspect for damage:
    • Check the battery for any signs of damage. If the battery is cracked or leaking, it may need to be replaced.
  4. Neutralize with baking soda:
    • Make a paste by mixing baking soda with a small amount of water. Ensure it’s thick enough to adhere to the battery corrosion.
    • Apply the paste to the corroded areas on the battery terminals. The baking soda will help neutralize the acidic corrosion.
  5. Scrub with a brush:
    • Gently scrub the corroded areas with an old toothbrush or a small brush. Be cautious not to apply too much pressure to avoid damaging the battery terminals.
  6. Wipe away residue:
    • Use a damp cotton swab or cloth to wipe away the baking soda residue and corrosion. Ensure the battery terminals are clean and dry.
  7. Vinegar (optional):
    • If the corrosion is stubborn, you can dip the toothbrush in vinegar and gently brush the affected areas. Vinegar can help dissolve the corrosion, but be cautious as it is an acid.
  8. Dry thoroughly:
    • Make sure the cleaned battery terminals are completely dry before reinserting the battery into the device.
  9. Reinstall the battery:
    • Once the terminals are clean and dry, reinstall the battery into the device.
  10. Dispose of old batteries properly:
    • If the battery is damaged or leaking, dispose of it properly according to local regulations. Many communities have specific recycling programs for batteries.

Always follow safety guidelines and recommendations from the device manufacturer when dealing with battery corrosion. If you’re unsure or uncomfortable, it’s advisable to seek professional assistance.
