Knowing how to clean battery terminals can help prevent starting problems and electrical issues. First, turn off your vehicle and disconnect the battery cables. Mix baking soda with water and gently scrub corrosion using a wire brush. Rinse and dry completely before reconnecting. While this helps short-term, corrosion often returns due to deeper battery issues. At Gentry Automotive, we inspect your battery, terminals, and charging system to ensure long-lasting performance.
