How To Clean A Car Battery With Coke

Car batteries are an essential component in making sure your vehicle runs smoothly. However, over time, car batteries can become corroded and dirty, which can affect their performance. One popular method of cleaning car batteries is by using Coke. Yes, you read that right. Coke is not only a refreshing drink, but it can also be used to clean your car battery. In this article, we will show you how to clean a car battery with Coke.

What You Will Need

Before we get started, you will need a few things:

  • A bottle of Coke
  • A pair of gloves
  • A wire brush
  • A clean rag
  • A bowl of water

Step 1: Safety First

When working with car batteries, it is essential to take safety precautions. Make sure you wear gloves to protect your hands from any acid that may be present on the battery. Also, make sure the car is turned off and the keys are out of the ignition.

Step 2: Pour Coke Onto The Battery

Now it’s time to pour Coke onto the battery. Make sure you pour enough Coke to cover the corroded areas of the battery. Coke contains phosphoric acid, which can help dissolve the corrosion on the battery.

Step 3: Let The Coke Sit

After pouring the Coke onto the battery, allow it to sit for a few minutes. The acid in the Coke will start to break down the corrosion on the battery.

Step 4: Scrub The Battery

Using a wire brush, scrub the battery to remove any remaining corrosion. Be careful not to scrub too hard and damage the battery.

Step 5: Rinse The Battery

Once you have finished scrubbing the battery, rinse it with a bowl of water. Make sure you remove all of the Coke and corrosion from the battery.

Step 6: Dry The Battery

Use a clean rag to dry the battery. Make sure you remove all of the water from the battery before you move on to the next step.

Step 7: Reconnect The Battery

Now it’s time to reconnect the battery. Make sure you reconnect the positive and negative terminals correctly. Once the battery is reconnected, turn on the car and make sure everything is working correctly.
