Step by Step Guide on How to Clean a Car Battery

Step 1 : Disconnect the Car Battery

Before you clean the battery, you should disconnect it from the car’s system. The first thing to do is to identify the location of the battery. You can clean the terminals with a wire brush if there’s any signs of the corrosion. Use a socket or wrench to remove the negative cable (a black cable with a (-) sign) and the positive cable (a red cable with a (+) sign). Be sure to keep the cables in a safe place after removing them.

Step 2 : Clean the Battery Terminal Posts

The metal nubs and posts found on a car battery are prone to corrosion, oil and dust. You’ll notice the corrosion powder by its blue-white color. Wear a dusk mask if corrosion powder (sulfuric acid powder) seems to take long to move from the terminals. You can also sprinkle some cleaning spray on the corroded posts to eat away the corrosion by neutralizing the acid. Use a wire brush to clean the posts further until they appear shiny.

Step 3 : Clean the Battery Cable Ends

The next parts to clean after the posts are free of corrosion are the cable ends. Clean one cable end at a time to avoid connecting them to the post with a metal. You can also soak the shop towels with a cleaning agent and use them to wipe any dirt on the cable ends. The wire brush will help you clean the entire cable end. Once you’re through with the cleaning process, inspect the cable ends for loose connections, cracks or damages. Replace them if you accidentally cracked them.

Step 4 : Reinstall the Battery Cable Ends and Cover

After ensuring that the terminal posts, cable ends and other parts of the car battery are clean, reinstall the cable ends. Attach the positive cable to the positive terminal and the negative cable to the negative terminal using their respective cable ends. Don’t apply a lot of pressure on the cables when tightening them since they can break. If your car battery has a cover, be sure to reinstall it after reinstalling the cable ends.

One more point

Car batteries require a lot of care and attention when you’re cleaning them. Tools such as sockets, wrenches, wire brushes, cleaning sprays and shop towels can help you clean them effectively. Before cleaning, be sure to disconnect the battery. Proceed with cleaning the terminal posts and cable ends. Complete the process by reinstalling the battery cable ends and cover.
