If you’ve spent any time under a hood you’ve seen crusty nasty battery terminals and may have thought nothing over it or simply brushed some off and waited for it to appear again. Cleaning the battery terminals is great preventative maintenance and prevents your car from having charging starting issues that end up costing way more to diagnose in the future. Let me run this as an example- battery had some minor corrosion on the terminals, always cleaned off superficially; corrosion spread into the battery cables causing a no start issue that took way longer than it should have to figure out.
Good thing you can remove battery corrosion on your own but, still, the best option for you is to replace the battery. For quality replacement batteries, visit Auto Parts Warehouse: https://bit.ly/2IXDz9h
So how to clean corroded battery:
- First of all wear gloves and safety glasses and remember that battery acid is unfriendly stuff and needs to stay off your car and you or anything else.
- Disconnect the battery safely and secure the cables so they do not come in contact with the battery on accident; start with the negative cable first.
- Create a solution of baking soda and water into a paste and use an old toothbrush to clean up the terminals and cables. Alternatively, you can also clean battery terminals with Coke. Use some Coca-Cola to pour on the terminals of the battery and the cables. Follow both with a wire brush to clean battery corrosion.
- Rinse everything thoroughly with water minding any electrical connections and not getting excess water anywhere it shouldn’t be. Dry off the battery.
- Reconnect the cables starting with the positive first and then the negative and secure them properly.
- Consider spraying a battery terminal protectant to prevent future corrosion.
Sometimes the corrosion is so bad that it will necessary to replace the terminals on the cables or the cables themselves, a properly maintained battery and cables will last a long time so don’t skip this if its needed and try using badly corroded terminals that may not tighten properly on the battery.
