The battery terminals on your vehicle’s battery develop corrosive buildup over time, especially if you don’t clean the terminals. Baking soda neutralizes this acid corrosion and completely removes it from the battery.
Combine equal parts baking soda and warm water to form a thick paste. Disconnect the terminals from the battery and wipe this solution around the terminals. Remove the baking soda with a towel dipped in warm water.
Prevent acid corrosion from building back up on your battery terminals with petroleum jelly. Once you’ve removed the baking soda, dry the terminals and reconnect. Dab a small amount of petroleum jelly on each of the terminals.
Always use caution when working around a car battery because it does contain acid. If acid accidentally drips on your clothing, wash in a solution of baking soda and water immediately. This helps neutralize the acid and keep it from eating through your clothing.
