What Is Battery Corrosion?

Battery corrosion occurs over time when specific chemical reactions occur at the battery’s terminals. It usually starts as an oxidation process caused by electricity, heat, and certain chemicals. It then progresses to more significant damage caused by the chemistries involved with the battery over time.

Corrosion of battery terminals can appear as a crystallized mass of white or greenish-white powdery material that can be easily wiped off.

Why Does My Car Battery Keep Corroding?

Corroded Car Battery

Corrosion on the terminals of your car battery is often caused by acid fumes that build up over time. When this happens, the lead plates and lugs inside your battery become exposed to the acid and begin to corrode. In addition, the hose clamps used to secure the battery will often start to corrode due to exposure to the elements.

A second common culprit for car battery corrosion is a lack of maintenance. When you ignore basic maintenance for your car battery, such as regular cleaning and charging, you’ll start to experience a build-up of sulfate deposits which can also corrode the terminals.

Neglecting to maintain your battery can also lead to excessive discharging and can lead to damage of the lead plates and terminals.

Car batteries may also begin to corrode if you are in an environment with a high level of humidity or salt, such as near the ocean or in a highly industrialized area. The combination of moisture and salt can greatly increase the rate of corrosion and can severely damage your battery.

Finally, a car battery will corrode if it’s not receiving the proper voltage. If your car battery can’t maintain a charge, then your car won’t be able to start and the corrosion on the terminals will continue to worsen.

How to Clean Car Battery Corrosion

Battery corrosion can be dangerous if you don’t take the proper safety precautions and know what to do when cleaning it. Take your time, be safe, and follow the steps above for a successful cleaning.

1. Put on safety glasses, rubber gloves and long-sleeve clothing. It is important to take safety precautions when dealing with batteries.

2. Lift the hood of your car and locate the battery. Take off the negative and positive terminals and ensure they are battery corrosion-free.

3. Use a stiff-bristled brush to scrub away the corrosion. Ensure you do not touch any metal terminals or cables with the brush.

4. Once the corrosion has been removed, use a clean cloth to wipe down the terminals. Make sure all the dirt and debris have been taken off.

5. Reattach the terminals and cable to the battery with a crescent wrench. Make sure you attach them in the correct position.

6. Clean the area around the battery with a damp cloth and allow it to dry completely before replacing your car’s hood.

How to Clean Car Battery Corrosion with Baking Soda

Here is a step-by-step guide on how to clean car battery corrosion with baking soda:

Step 1: Remove the Battery

First, remove the car battery from its compartment and place it on a flat surface. Be sure to unplug the terminals and remove any plastic guards or covers.

Step 2: Create a Baking Soda Paste

Mix baking soda with water until it forms a paste. Then, apply the paste to the battery posts and terminals. Make sure the baking soda paste covers all of the corrosion buildups.

Step 3: Let the Baking Soda Work

Allow the baking soda paste to sit and work on the corrosion buildup for at least 15 minutes. This will help the baking soda to break down and loosen the buildup.

Step 4: Scrub and Rinse the Battery

Remove the baking soda paste from the battery posts and terminals using a non-metallic brush. Then, rinse the battery with clean water.

Step 5: Clean the Battery Compartment

The battery compartment should be cleaned to remove any lingering debris or toxic residues. Use a cloth and cleaning solution or baking soda paste to clean the compartment.

Step 6: Re-Install the Battery

Once everything is dry, you can reinstall the battery. Be sure to lubricate the terminals and then plug them in.How to Clean Car Battery Corrosion without Baking Soda

Cleaning off corrosion is especially important if your battery has been exposed to moisture or you plan to replace an old battery with a new one.

Step One: Prepare the Area

Before you start, you should put on eye protection. Additionally, you’ll need to prep the area for your cleaning job. To do this, wear old clothes, lay down some drop clothes, and remove the clamps from the battery.

Step Two: Scrub the Battery

Now that the area is prepped, you must scrub off the corrosion. Use a brush with stiff bristles and a cleaning solution to do this. Mix the solution according to the instructions on the label, and use the brush to scrub away any rust or buildup.

Step Three: Rinse the Battery

Once the rust and residue have been scrubbed away, rinse the area with clean water. This will ensure that all of the cleaning solutions have been removed.

Step Four: Apply the Cleaning Agent

Now that the area is debris-free, you need to apply the cleaning agent. You can use materials like white vinegar, citric acid, or borax. These are readily available materials and won’t irritate the battery clamps.

To apply, take a contaminated battery piece and soak it in the solution for about 5 minutes. Then, with a wire brush, scrub away the corrosion. After that, rinse off the area with clean water.

Step Five: Grease the Battery

Once the battery is clean, put some grease on the clamps. This will produce a barrier and protect the clamps from corrosion in the future.

Step Six: Reattach the Clamps

Once you’ve completed the job, reattach the clamps to the battery. Use a wrench or similar tool to make sure they’re properly secured.

How to Clean Car Battery Corrosion with Coke

Here’s a step-by-step walkthrough on how to clean car battery corrosion with Coke.

Step 1: Put on Protective Eyewear and Gloves

Safety first—you don’t want the acidity from Coke splashing into your eyes or onto your skin. Wear rubber gloves and safety glasses before you begin.

Step 2: Unscrew the Battery Clamps

Inspect the two battery clamps that are attached to your car battery terminals and unscrew them if necessary.

Step 3: Scrub off Existing Corrosion

Using a stiff copper-bristled brush, gently scrub off any existing corrosion that’s built up on the battery terminals.

Step 4: Prep the Battery Terminals

Apply baking soda to the terminals in order to neutralize the acidity. This will also foam up instantly and help remove residue.

Step 5: Soak the Terminals in Coke

Use a bowl or tray and soak the exposed wires in soda for around 15 minutes. The acidity in Coke will help to break down your car battery corrosion.

Step 6: Rinse and Dry the Terminals

Afterwards, use a damp cloth and rinse the exposed wires. Use a clean piece of cloth to dry them off afterwards.

Step 7: Add Petroleum Jelly

To prevent new corrosion, apply petroleum jelly to the terminals. This will act as an insulator and keep your car battery in the best condition for longer.

Step 8: Reattach the Clamps

Reattach the two clamps to the terminals, securing them tightly.

How to Clean Corroded Battery Terminals in Electronics

The Corrosion of battery terminals in electronics can cause permanent damage if left unchecked. It’s important to clean these off promptly to prevent any serious damage.

1. Ensure Device Is Unplugged and the Power Source Is Shut Off

Before cleaning the corroded battery terminals, ensure the device is powered off and unplugged. It may be necessary to remove the battery from the device altogether.

Car Battery Corrosion Prevention

Firstly, it is recommended that you regularly clean the terminals of your car battery with a wire brush and baking soda. Both have slight abrasive and de-greasing qualities that are great for removing any dirt and contaminants that build up on the terminal posts. This will prevent corrosion from happening.

The second way to prevent car battery corrosion is to ensure the battery is properly charged. Overcharging and discharging the battery can cause irreversible corrosion, drastically reducing the life of your battery. When checking your battery’s charge level, it is best to use a voltmeter.

The third way to avoid corrosion is to keep your battery out of extreme temperatures. Both extreme cold and extreme heat can cause permanent damage to the metal and cause corrosion. It’s also advised that you not store your battery near chemicals such as acid, bleach, and petroleum products. These can also hasten the corroding process.

Finally, one of the best ways to prevent car battery corrosion is to ensure the battery is correctly maintained. This means you should regularly check fluid levels and ensure the electrolyte is still potent. If the battery is kept properly maintained, then the life of the battery will surely be improved.

Best Car Battery Corrosion Cleaner
