David Davis asked 5 months ago
I'm dealing with a stubborn issue. My car's battery terminal is heavily corroded, making it impossible to remove. I've tried cleaning it with a wire brush, but it's still stuck. Is it okay to use CRC Battery Cleaner on the terminal while it's still connected? I'm also concerned about the safety of driving with a corroded battery terminal, as I have a long journey ahead. Any advice on how to handle this situation would be greatly appreciated.

Hey there, David! Dealing with a corroded battery terminal can be tricky, but here's a step-by-step guide to help you out:
  1. Safety First: Ensure your car is turned off and the keys are removed. Wear protective gloves and safety glasses.
  2. Initial Cleaning: Continue using the wire brush to remove as much corrosion as possible.
  3. Applying CRC Battery Cleaner: It is generally safe to apply CRC Battery Cleaner to the terminal while it's connected. However, ensure you're in a well-ventilated area and avoid direct contact with the battery acid.
  4. Alternative Methods:
    • Coca-Cola Trick: Surprisingly, Coca-Cola can help dissolve corrosion. Pour a small amount over the corroded area and let it sit for a few minutes, then clean off.
    • Hot Water: Boiling water can also help dissolve the corrosion. Carefully pour it over the terminal and let it work.
  5. Using a Battery Terminal Puller: If the terminal is still stuck, consider using a battery terminal puller. This tool can help remove the terminal without causing damage.
  6. Rinsing and Drying: After applying any cleaning solution, rinse the area with water and dry it thoroughly.
  7. Re-attaching the Terminal: Once cleaned, reattach the terminal. Ensure it's snug but not overly tight.
  8. Driving Safety: If the corrosion is severe, it's advisable to fix this issue before embarking on a long journey. Corrosion can lead to poor electrical connections and potentially leave you stranded.
Note: If you're unsure at any point, it's always best to seek professional help. Safe travels and best of luck with your battery issue! Do let us know how you get on :-) Zack - Motor Verso Mechanics Team
