One crucial point to note is to ensure you wear the safety equipment before cleaning. Such as gloves, goggles, and a face mask, unless you don’t want to get your hands dirty. In addition, when it comes to car maintenance and care, safety is always the priority.

Let’s get started and follow the below steps. Easy peasy!

Step 1: Locate your car battery and disconnect all the cables

Open the hood of your car and find the corroded battery. After then, remove the two connected cables from it.

Make sure to put a cloth or rag. It will thus work as double protection so that you don’t shock yourself while handling them. Alternatively, you can knot the wires to keep them out of the way if you want.

If the corrosion is too severe for you to reach the cables, sprinkle some coke on it and wait a few minutes before touching it again.

Step 2: Apply the Coke and allow some time to settle and work

Put the homemade Coke in a spray bottle. After then, fill it with water. It will clean any portions of the battery that you spray it on.

Make sure to spray evenly over each area, one at a time. Lastly, let Coke take care of the rust and grime while you see the magic happening.

Step 3: Rinse it off

Here, your first task is picking up the brush and cleaning up the places where the coke is sprayed. Move in a circular, up-and-down, or another way down.

Moving on, your car battery’s accumulation needs to be removed from the terminals of the batteries. Remember to use just moderate force—neither too high nor too low.

Hold a cup in a different hand to catch the debris brushed off. Throw away the cup in the trash bin so you won’t have to clean it up later.

Also, please have patience with this phase, as it will take some of your time. After all, to successfully complete this step, you must pay close attention to every nook and corner.

However, you will need to scrub the automobile battery for a longer or shorter period, depending on how much it has been rusted. As you work, add additional coca cola whenever required.
