Keep Your Toilet Tank Clean and Fresh with Baking Soda

toilet tank

Have you ever wondered why some people put baking soda in their toilet tanks? Well, there’s a good reason for it.

First off, it’s important to understand that the toilet tank is part of the toilet that holds the water that’s used to flush the toilet. Inside the tank, there are a variety of different parts, including the fill valve, the flush valve, and the flapper. All of these parts can become dirty and gunked up over time, which can lead to a variety of problems, such as leaks and slow flushes.

This is where baking soda comes in. Baking soda, also known as sodium bicarbonate, is a natural cleaner that can help to break down and remove buildup and grime from the various parts inside the toilet tank. It’s also an excellent deodorizer, which can help to freshen up the smell of the bathroom.

To use baking soda in your toilet tank, simply remove the tank lid and pour about a cup of baking soda into the water. You can also use a toilet brush to scrub any areas of the tank that have buildup or stains. Once you’re finished, flush the toilet a few times to rinse out the baking soda.

It’s a good idea to do this cleaning at least once a month to maintain the proper functioning of the toilet and prevent any blockage in the future.

What Does Baking Soda in the Toilet Tank Do?

Baking soda in a toilet tank can help to freshen the water in the toilet bowl and prevent unpleasant odors. When added to the tank, baking soda reacts with the water and creates a slightly alkaline solution, which can help to neutralize acidic waste that can cause odors.

Baking soda also has mild abrasive properties, so it can help to clean the toilet bowl over time. However, it’s important to note that adding too much baking soda to the tank can potentially cause damage to the toilet’s components, so it’s best to use it in moderation.

Why Use Baking Soda?

One of the main benefits of using baking soda to clean your toilet tank is that it is a natural, non-toxic alternative to chemical cleaners. 

Chemical cleaners can be harsh and potentially harmful to your pipes, as well as the environment. Baking soda, on the other hand, is a safe and effective way to clean and deodorize your toilet tank without any negative side effects.

In addition to removing buildup and grime from the various parts inside the toilet tank, baking soda can also help to remove stains. The abrasive nature of baking soda can help to lift away tough stains caused by mineral buildup or hard water, leaving your toilet tank looking clean and fresh.

Another benefit of using baking soda in your toilet tank is that it can help to extend the life of the various parts inside. 

Over time, mineral buildup and grime can cause damage to the fill valve, flush valve, and flapper, leading to leaks and other problems. By regularly cleaning your toilet tank with baking soda, you can help to prevent this damage and keep your toilet running smoothly for longer.

It’s worth mentioning that you can use baking soda with other household items to make a powerful cleaning solution. 

For example, a paste made of baking soda and vinegar can be used to scrub away stains and buildup. Another alternative is to mix baking soda and lemon juice to create a fresh-smelling cleaner that will help to remove stains and odor.

Also, if you have a septic system, you should be careful when using baking soda in your toilet tank, as it can disrupt the balance of the bacteria in the system.

Won’t Baking Soda Clog my Toilet Tank?

Baking soda is a fine powder, and if not used correctly, it can clog the tank. However, if used in the proper amounts and in the proper way, it is unlikely to clog the tank.

When using baking soda in the toilet tank, it’s important to use the appropriate amount. A general guideline is to use about a cup of baking soda per tank. Any more than that can cause issues, and if your tank is clogged, it’s better to remove and clean it entirely, as well as use a professional plumber service.

It’s also important to note that while cleaning the tank with baking soda and scrubbing it with a toilet brush can help remove buildup, it can’t guarantee that you’ll remove all of it, especially if the buildup is already hard and solid. It’s not recommended to leave the baking soda to sit in the tank for a long period as it may cause clogging.

Also, after cleaning the tank, it’s important to flush the toilet multiple times to ensure that all of the baking soda is removed from the tank and the pipes.

In summary, using baking soda in the toilet tank can be a great way to remove buildup and freshen up the bathroom, as long as you use the appropriate amount and flush the toilet thoroughly afterward to prevent clogging.

When to Call a Plumber

While using baking soda to clean your toilet tank can be a great way to keep it running smoothly, it’s important to know when it’s time to call in a professional plumber.

  • If your toilet is leaking or running constantly, this is a sign that there may be a more serious issue that needs to be addressed by a professional. A leaking toilet can waste a lot of water and cause your water bill to skyrocket, so it’s important to get it fixed as soon as possible.
  • If your toilet is clogged and won’t flush, don’t try to fix it yourself by using chemical drain cleaners. These products can be harmful to your pipes and may even cause more damage. Contact a plumber instead.
  • If your toilet tank is damaged, such as cracks or holes, it’s best to have a plumber take a look. A damaged tank can lead to leaks and other problems, and it’s not something that you should try to fix on your own.
  • If you’re experiencing any strange noises or odors coming from your toilet, it’s best to have a plumber check it out. These can be signs of a serious problem that needs to be addressed.

It’s also important to note that, while cleaning the toilet tank with baking soda can prevent some issues, it cannot fix everything. Some problems might need specialized equipment or knowledge that only a professional plumber can provide.

Remember that regular maintenance and cleaning can prevent a lot of toilet-related issues. If the problem persists despite your efforts and you are unsure about what to do, it’s always best to call a professional plumber for help.


So, to wrap things up, we’ve learned that putting baking soda in your toilet tank is a simple and effective way to keep it clean, prevent leaks and odors, and save yourself a costly plumber’s visit. 

But, it’s important to remember that when it comes to plumbing problems, there are some things that baking soda just can’t fix. So if you’re dealing with a leaky toilet, a clogged pipe, or a damaged tank, it’s time to call in the big guns (or in this case, a professional plumber)

Another thing to remember is that regular cleaning and maintenance can prevent a lot of problems in the first place. So don’t be afraid to roll up your sleeves and give your toilet tank a good scrub down with baking soda every once in a while. It’s like giving your toilet a spa day, without the aromatherapy candles.

And lastly, if you’re feeling fancy and want to step up your cleaning game, you can add essential oils to your baking soda mixture for a little extra deodorizing power. Imagine the lingering smell of lavender, lemon, or peppermint in your bathroom. It’s like having a spa in your own home.

So there you have it, folks! Baking soda is a powerful ally in the battle against dirty and smelly toilet tanks.

Now go forth, and give your toilet tank the spa day it deserves.
