Warning
Car batteries contain sulfuric acid, which is highly caustic. Wear gloves and goggles or a face shield when working with them.
Step 1: Remove battery cables
Remove the battery cables from the battery terminals by loosening the nut on each cable clamp. Use vice grips to remove the battery cables if there is a lot of corrosion on the battery.
Tip
Always remove the cable clamp from the negative terminal first.
Step 2: Apply some baking soda
Place some baking soda on the terminal posts. Dip a toothbrush in water and scrub the baking soda into the terminal posts and cable clamps. Dry everything with a clean, disposable, lint-free rag.
Tip
If the toothbrush doesn’t do the trick, purchase a battery terminal cleaner brush from an auto parts store. Clean the insides of the cable clamps with the cleaner packaged with the brush.
Step 3: Add some grease
Place some grease or petroleum jelly on the posts, battery cables, and clamps. This will slow down the formation of corrosive deposits.
Step 4: Replace the clamps
Replace the positive clamp first, followed by the negative one. Cover the positive terminal with a rubber boot or plastic shield.
Step 5: Check the water level
Check the battery’s water level every few months. Refill with distilled water to the bottom of the refill hole as needed. Don’t use tap water, which will corrode the terminals.
