Corrosion is a problem that occurs on a battery. Old batteries have a liquid inside that leak out and cause the metal to stick to other battery parts. The car will not work if the corrosion is bad, so you need to take it to a mechanic for help. You can fix this problem with Coca-Cola by pouring it on the battery and wiping it off with a rag.

Moreover, a corroded car battery will eventually prevent you from starting the vehicle to take it out on rides. Therefore, you must address it as soon as you notice corroded battery terminal symptoms.

So, how to clean a car battery with Coke? Take the Coke and pour it on the battery. You might even want to take off the battery cover first. Put the Coke on the terminals for about an hour before taking it off to see if it helps. If you have a battery that’s not worth fixing or can’t get to the terminals, pour it on the outside of the car. Put on some rubber gloves before performing this.

Before going through the step-by-step process, knowing some things about Coca-Cola is necessary.

Does Coke remove corrosion?

Yes, Coca-Cola is a wonderful product that can remove corrosion from car battery terminals.

Coca-Cola contains carbonic and phosphoric acid ingredients, which are great for dissolving rust. In addition, the sweet syrupy taste covers up any harsh chemical flavors, so it won’t be so difficult to have this drink touch against your lips.

The citric acid in Coke can also help cleanse the corrosion and leave a protective film behind so that it doesn’t come back.

Can I pour Coke on my car battery?

How to Clean a Car Battery with Coke: Step By Step Process

Coca-Cola contains acid, which can be used for cleaning purposes in various ways. In the following section, we will discuss how you can use Coke to remove corrosion from your vehicle battery terminals and the metal surfaces of the battery box.

Let’s take a look at the step-by-step guide…

Step 1: You will need to find your car battery and take the cables off

To start, pop up your car’s hood and find the corroded battery. Disconnect both cables from it. Put them on a cloth or rag so you don’t shock yourself while touching them. You can also tie the cables out of the way if you want to.

As long as they won’t hurt themselves when touching the battery! If there is too much corrosion for you to get to the cables, add some coke on it and wait for a couple of minutes before touching again.

Step 2: Apply the coca-cola and let it work.

Put the coca-cola you made into a spray bottle. Put some water in it first. Spraying it on parts of the battery will make them clean. Do this by spraying one part at a time and evenly. Let the coca-cola work on the dirt and corrosion.

Step 3: Rinse it off.

Grab the brush. Clean the areas that you sprayed Coke on. Use side-to-side, up-and-down, or circular motions as needed.

Top Tip: Make sure you have a good brush for cleaning. You should only use the toothbrush if you find any other brush. We recommend that you buy brushes with stiff bristles. There are 3 good ones in the market: OXO Good Grips Deep Clean Brush Set, Amazer Scrub Brush Comfort Grip, Flexible Stiff Bristles, and Chemical Guys ACCG25 Induro 7 Heavy Duty Nifty Interior Carpet/Upholstery Detailing Brush.

The buildup on your car battery should be coming off. Do not forget to use moderate force. Put a cup on the ground to collect the gunk that comes off. This way, you don’t have to clean up later; throw out the cup of gunk.

Before you start scrubbing:

  1. Take a while to clean the battery.
  2. Spend more time on worse things.
  3. After putting the coca-cola on, make sure you scrub from top to bottom.

You need to make sure everything is clean, and there’s no part left out!

If you have a hose, use it to rinse off the battery and its area. Rinse until no more suds or dirt is coming off.

Step 4: Dry it off.

Wipe down the battery with a dry cloth. Make sure all the areas are clean and free of any liquid.

Now that your car battery is clean, you can put it back in the car. When putting in the battery, make sure it’s in securely by banging or shaking it. If there are any rattles, they may not be locked into place correctly. And that’s how easy it is to clean your corroded car battery.

If you want to keep your battery clean, then be sure to store it in a cool, dry place. If you live in a hot climate, keep it covered to prevent heat from getting to it.

Also, remember that your battery will corrode if not used. And the more damage there is on the battery, the faster corrosion and rust will form.

With that, you have gone through all the steps to clean the battery with Coke. It was easier than you expected.

Can you pour Coke on a car battery when the car is running?

No, because there are sparks. It would be best if you disconnected the cable with electricity first. Next, put Coca-Cola over any rust or corrosion on your battery. Then bubbles will come out of it. Let it stay like that for 10 minutes. Then add water to the battery, and you will see bubbles again. But this time, it is good bubbles so don’t touch them or move anything near them.


It’s important to have a clean car battery for the start of summer. You can do this by mixing Coke and water in an old soda bottle, shaking it up until you get all the bubbles out then pouring it over your car battery. Let it sit for five minutes before wiping off with a paper towel or cloth. Finally, rinse thoroughly with cold water after allowing time to dry overnight. This is one way that people use Coke products when cleaning their cars.
