Car batteries tend to corrode if they are not cleaned on a periodic basis.
Exposure to moisture is the main reason behind this phenomenonIf left unattended, the rusted parts of your car battery can hinder the smooth performance of your car.
Check your Battery
Owing to a corroded car battery may often cause difficulty in starting your car. In order to check the condition of your battery, you would need to examine it directly.
- Turn off the car before you open the hood of your car. This can avoid untoward damage to the cables inside.
- Check the nature of the terminal configuration your battery has. This is important to determine the type of wrench you would need.
Remove the Cables
For batteries that have their terminals on the side, you would require an 8mm wrench for removing the cable nuts. And for batteries that have terminals on the top, you need to get a 10mm wrench.
- Once you find the right kind of wrench, start loosening the negative cable clamp and slowly detach the cable.
- Repeat the same procedure for the positive cable clamp. Slowly pull up the cables by twisting them if needed.
Look for Cracks
When you are removing the battery for a general cleanup you can easily detect issues like cracks or dents.
- Check the top and edges of your battery for small cracks or openings. Such cracks can lead to acid leakage which can be dangerous.
- If you happen to find any cracks or dents, you can abandon the cleaning process because you would need to replace the entire battery.
Prepare a Safe Cleaning Solution
Once you have located the areas that are rusted, you need to make arrangements for cleaning them in a safe manner.
- Take a cup of hot water and add 1 tablespoon of baking soda to it. Stir the mixture to create a strong cleaning solution.
- Apply the solution to the corroded parts of the battery using an old toothbrush. Scrub gently to loosen the layer of dust and debris.
Clean the Cables and Clamps
Corroded batteries often require thorough cleaning as the rust tends to spread to different parts of the battery including the cable tips.
- To clean corroded cable ends you can immerse them in the hot baking soda solution and then scrub gently with the brush.
- Also, rub the baking soda solution around the posts and battery clamps to remove any trace of corrosion.
Rinse with Cool Water
After scrubbing the battery and its parts with a baking soda solution, you need to rinse thoroughly with cool water.
- Rinsing with cold water is an effective way to dislodge the corroded layers that have been loosened up with hot water treatment. Also, clean the cables and clamps with cold water.
- After rinsing, use a clean cotton cloth to soak up all the water. Wipe again using another dry cloth to remove the leftover trace of moisture.
Lubricate the Battery Terminals
In order to prevent corrosion in the near future, you need to lubricate the metallic parts around the battery terminals, clamps, and posts.
- You can use a battery terminal protector spray to lubricate the areas that are prone to corrosion.
- Alternatively, you can simply apply some petroleum jelly to lubricate the metal parts.
- Now you can connect the cable clamps and position the battery back in its original place.
- In the case of an emergency, you can clean the battery using cola and water. You can do it by simply loosening the terminals.
- While cleaning the clamps examine them carefully. If you detect any tear or crack then you would need a replacement.
