How to Clean Corroded Battery Terminals: A Step-by-Step Guide for a Better Battery Performance


If you're like me, you've probably noticed that your car's battery terminals have become corroded over time. Not only does this make your car look unsightly, but it can also cause problems with the battery's performance. Fortunately, cleaning corroded battery terminals is a simple process that can be done with household items. In this post, I'll walk you through the steps of how to clean your car's battery terminals and give you a few interesting facts about this process.


Here's What You'll Need:

  • Water

  • Baking soda

  • An old toothbrush or wire brush

  • Battery terminal cleaner or vinegar

  • Grease or petroleum jelly

Step 1: Disconnect the Battery

Before you start cleaning, you need to disconnect the battery. Make sure you disconnect the negative cable first and then the positive cable. This will prevent any electrical short circuits from occurring.


Step 2: Mix Baking Soda and Water

In a small bowl, mix 2 tablespoons of baking soda with enough water to make a paste. Baking soda is a great cleaning agent because it's gentle enough to clean the battery without damaging it, but strong enough to dissolve the corrosion.


Step 3: Apply the Baking Soda Paste

Using a toothbrush or wire brush, apply the baking soda paste to the corroded areas of the battery terminals. Make sure you cover the entire corroded area.


Step 4: Let it Sit

Let the baking soda paste sit on the battery terminals for about 10 minutes. This will give it time to dissolve the corrosion.


Step 5: Rinse with Water

After 10 minutes, rinse the baking soda paste off the battery terminals with water. Make sure you rinse thoroughly to remove all of the baking soda.


Step 6: Clean with Battery Terminal Cleaner or Vinegar

If you have battery terminal cleaner, use it to clean the battery terminals. If you don't have battery terminal cleaner, you can use vinegar. Apply the battery terminal cleaner or vinegar to a cloth and wipe the battery terminals clean. This will help remove any remaining corrosion and help prevent future corrosion.


Step 7: Apply Grease or Petroleum Jelly

After cleaning the battery terminals, apply a thin layer of grease or petroleum jelly to the terminals. This will help prevent future corrosion and keep the terminals clean.


Step 8: Reconnect the Battery

Finally, reconnect the battery. Make sure you connect the positive cable first and then the negative cable.


And there you have it! Cleaning your corroded battery terminals is a simple process that can be done with household items. By following these steps, you'll help keep your car's battery in good condition and prevent any problems with its performance.

Interesting Facts About Corroded Battery Terminals:

  1. Corrosion is caused by a chemical reaction between the battery acid and the metal terminals.

  2. Corroded battery terminals can cause problems with the battery's performance, such as a slow engine start or a weak electrical system.

  3. Cleaning your battery terminals regularly can help prevent corrosion and extend the life of your battery.

Personal Story:

I remember the first time I noticed that my car's battery terminals were corroded. I was getting ready to go on a road trip and I noticed that my car wasn't starting as easily as it used to. I took a look under the hood and saw that the battery terminals were covered in a white, powdery substance. I had heard that this was corrosion, so I went to the store and bought some baking soda and vinegar. I followed the steps I outlined above, and to my surprise, the cleaning process was quick and easy. Not only did my car start easier after I cleaned the battery terminals, but it also had a stronger electrical system. I was so impressed with the results that I made a mental note to clean my battery terminals regularly to prevent future corrosion.


Since that day, I've cleaned my battery terminals several times and have shared the process with friends and family. They've all been amazed at how simple it is and how much of a difference it makes in their car's performance.


In conclusion, if you're experiencing problems with your car's battery performance, take a look at the battery terminals. Chances are, they're corroded. By cleaning the corroded battery terminals, you'll help keep your car's battery in good condition and prevent any problems with its performance. And, who knows, you might even learn a thing or two about batteries in the process!
