Maybe you’ve heard another hack from somewhere, this time involving whether Coke can clean toilets. I’ve done all the research for you, so keep on scrolling down to learn more!

Does Coke Clean Toilets?

Coke is not only a refreshing beverage but also doubles as an effective toilet cleaner. Coke has acidic ingredients which are phosphoric and carbonic acid ingredients, and those ingredients are enough to dissolve stubborn stains in your toilet bowl. To do so, you’ll only need to soak your toilet in a can of Coke for two hours or more. 

If you’re curious to know more about Coke and its toilet-cleaning abilities, how to use coke to clean your toilet, and more, then keep on reading!

Why Can Coke Clean A Toilet?

Coke is a beverage that is highly acidic, falling in the pH range of 2.6 to 2.7. Due to its high level of acidic properties, Coke is more than enough to remove stubborn stains from your toilet.

There are two particular acids responsible for making Coke an effective toilet cleaner. First is phosphoric acid, which is commonly used in the industry as an acerbic treatment to remove mineral build-up.

Second is carbonic acid, which is another popular ingredient in many cleaning products. Carbonic acid is also responsible for the fizz and bubbles you get upon opening your Coke.

Combining these two acids is a foolproof way to dissolve hard-to-reach toilet stains. Carbonic acid will form a strong force that breaks the debris apart while the phosphoric acid will clean out any grout and dissolve stain residue.

Can You Clean A Toilet With Coke And Baking Soda?

If you think that Coke is not strong enough to completely disintegrate your toilet stains and grease, then combining Coke with baking soda can work.

Baking soda is another home cleaning agent that acts as an abrasive, and using baking soda with Coke can be a powerful stain remover.

To do this, you’ll need to get a cup of baking soda and sprinkle the baking soda all over your toilet bowl.

Pour the bottle of Coke directly into the toilet, making sure that all particles of baking soda are making contact with the cola. You’ll quickly see a chemical reaction of bubbles, which is normal.

Let the Coke and baking soda mixture sit in your toilet for an hour or so. Finally, you can use the scrubber to gently brush any remaining stain residue then flush the toilet.

This mixture not only helps you remove stubborn stains and smells but also leaves your toilet clean and polished.

Does Coke Zero Clean Toilets?

Coke Zero is another variant of the Coca-Cola line which can also be a toilet cleaner. Plus, Coke Zero won’t leave a sticky residue that attracts insect mess.

This sugar-free variant also contains phosphoric acid and is carbonated, so it will work like regular Coke when removing stains.

However, Coke does not have any sugar which when left alone will leave only a sticky film in your bowl.

For reference, Diet Coke will also suffice as a home toilet cleaner. Point is, Coke and all its varieties are capable of making your toilet clean and stain-free.

Does Coke Remove Limescale From Toilet?

Your can of Coke is not only capable of removing dark stains, but can also dissolve the white limescale film in your toilet bowl.

This is not an easy feat, because limescale, which is the chalky deposit on the surface of your toilet bowl, buildup is quite stubborn and only accumulates over time.

To remove the limescale, start pouring Coke from the edges of your toilet bowl into the toilet bowl itself. Make sure you soak every inch of the toilet’s surface, then let the Coke sit overnight.

When you wake up, flush the toilet and you’ll find that the limescale has disintegrated, leaving you with a smooth bowl surface. Rinse the fizz thoroughly to avoid any sticky leftovers.

How Long Do You Let Coke Sit On The Toilet?

If your goal is to sanitize your toilet and remove brown stains, then you can let the Coke sit in the toilet for two hours.

However, this generally depends on how stubborn the stain is, or how large the affected area is.

You can also leave the Coke in the toilet overnight if you want to ensure that all debris will dissolve.

There’s no harm in leaving Coke in the toilet for a long time as long as you know how to clean up afterward.

How Much Coke Does It Take To Clean A Toilet?

One 12-ounce serving of Coke will be enough to cover the whole surface of your bowl if you have a standard-sized toilet.

If you have a bigger container of Coke stashed around, just measure 1.5 cups of Coke and pour the Coke into the bowl for a much-needed cleaning session.

Can Coke Clean Toilet Mold?

If you’ve had the misfortune of growing mold in your toilet bowl, then rest assured because Coke is an accessible remedy to this problem.

You’ll only need water, hydrogen peroxide, and a can of Coca-Cola to remove mold from the toilet.

To do so, just mix 1 part of hydrogen peroxide with water and spray the solution on the moldy surface.

Let the moldy part soak in hydrogen peroxide for at least an hour and then scrub to disturb the mold.

Follow this step by pouring in Coke to further dissolve the mold. You can also use Coke to reduce the scaling or stain left behind by the mold particles.

Does Coke Remove Hard Water Stains From A Toilet?

Coke is extremely effective in removing persistent water stains from the toilet, especially if you combine it with good old scrubbing by using a brush, such as a toilet brush.

Simply pour the whole can of Coke into the bowl, making sure that the top of the toilet has been soaked with Coke then let the Coke sit for a few hours.

Two hours will be enough soaking time, but you can leave the Coke in the toilet bowl for a longer time if you think your toilet will need to soak for longer.

Once you’ve decided that the Coke has soaked long enough, scrub your toilet vigorously with a brush, especially around the hard water stains.
