An alternative to baking soda paste is Coke. Yes, to clean battery terminals. Whichever cleaning solution you opt for, follow up with a wire brush to clean the more stubborn bits of corrosion.
- Common sense moment: Electrical connections do not like water. Rinse away the cleaner very thoroughly, but do take care not to splash water on other parts of the battery. Take a few moments to completely dry the battery with a clean rag.
