Car battery corrosion is a common problem that can lead to a variety of issues, including difficulty starting your car, decreased battery life, and even electrical fires. Fortunately, it is possible to clean car battery corrosion and prevent it from recurring.
What Causes Car Battery Corrosion?
Car battery corrosion is caused by a chemical reaction between the battery terminals and the air. When the battery is in use, hydrogen gas is produced as a byproduct. This gas can react with the lead in the battery terminals to form lead sulfate, which is a white, powdery substance. Lead sulfate can build up on the terminals and prevent the battery from making a good connection, which can lead to the problems mentioned above.
How to Clean Car Battery Corrosion
Cleaning car battery corrosion is a relatively simple process, but it is important to take safety precautions. Before you begin, make sure to wear gloves and eye protection. You will also need a few tools, including:
- A wire brush
- A baking soda solution (1 cup baking soda to 1 cup water)
- A clean rag
- A wrench or pliers
Step-by-Step Instructions
1. Disconnect the negative battery terminal. This will prevent any sparks or electrical shocks from occurring.
2. Use the wire brush to remove any loose corrosion from the battery terminals and the cable clamps.
3. Apply the baking soda solution to the terminals and cable clamps. Let it sit for a few minutes, then use the clean rag to wipe away the solution and any remaining corrosion.
4. Rinse the terminals and cable clamps with clean water.
5. Dry the terminals and cable clamps with a clean rag.
6. Reconnect the negative battery terminal.
7. Start your car and let it run for a few minutes to charge the battery.
How to Prevent Car Battery Corrosion
There are a few things you can do to prevent car battery corrosion from recurring:
- Keep your battery clean. Regularly check the terminals and cable clamps for any signs of corrosion, and clean them as necessary.
- Use a battery terminal protector. These protectors are available at most auto parts stores and can help to prevent corrosion from forming on the terminals.
- Avoid overcharging your battery. Overcharging can cause the battery to produce more hydrogen gas, which can lead to corrosion.
- Have your battery tested regularly. A battery that is not functioning properly is more likely to corrode.
Signs of Car Battery Corrosion
There are a few signs that you may have car battery corrosion, including:
- Difficulty starting your car
- Decreased battery life
- Electrical problems
- Corrosion on the battery terminals or cable clamps
What Happens if Car Battery Corrosion Is Not Cleaned?
If car battery corrosion is not cleaned, it can lead to a number of problems, including:
- Battery failure
- Electrical fires
- Damage to the battery terminals or cable clamps
When to Call a Professional
If you are not comfortable cleaning car battery corrosion yourself, or if the corrosion is severe, it is best to call a professional. A mechanic can safely clean the corrosion and make sure that your battery is functioning properly.
Wrapping Up
Car battery corrosion is a common problem, but it is one that can be easily prevented and cleaned. By following the tips in this article, you can keep your battery clean and corrosion-free, and ensure that it lasts for many years to come.
What You Need to Know
