Is It Safe to Put Fabuloso in Your Toilet Tank?

Last update:

You’ve probably noticed the hype surrounding a cleaning product Fabuloso and its reportedly miraculous effects on toilet performance. 

Thousands of social media users talk about the Fabuloso TikTok toilet hack, claiming it can make your throne cleaner. However, the hype also poses a serious question:

Is it safe to put Fabuloso in the toilet tank?

Yes, it is safe – but you shouldn’t do it. Putting Fabuloso in the tank can’t hurt you, but its purpose is not to sit in the tank. If you leave it there, Fabuloso will undermine the performance of your toilet tank, both short and long-term.

That’s the short answer but stay with us as we have a lot more to say about this topic.

The video that caused a social media frenzy earned over 5 million likes, 30 thousand comments, and 420 thousand shares.

What Does the Company Say?

Rather than listening to TikTok users, we need to see the manufacturer’s viewpoint on the Fabuloso toilet hack.

But honestly, there’s not much to hear from Fabuloso.

The company keeps it conservative and still doesn’t comment on the toilet tank video. Instead, they urge customers to read product labels and act accordingly. The bad news is that labels don’t say anything about putting Fabuloso in the toilet tank. 

We consulted the company’s FAQ page to investigate the Fabuloso toilet hack, and here are the official recommendations:

  • Fabuloso cleans floors, walls, bathrooms, living rooms, and almost every hard surface in your home
  • For bathrooms and walls: Use on a sponge and clean
  • Please always read the label for proper usage instructions

That’s pretty much all they say about how to use the product, but they do not specifically mention Fabuloso and the toilet hack. Even if it’s safe, the company’s representatives won’t say it openly.

Companies are conservative, and they don’t mess around with reputation that easily.

Two Reasons Why You Shouldn’t Put Fabuloso in the Tank

With or without the company’s stance on this topic, we can still identify two reasons you shouldn’t add Fabuloso to the toilet tank. 

Placing a Bottle in the Tank Leaves Less Room for Water

A typical flushing toilet launches 1.6 gallons of water per flush (GPF) directly to the toilet bowl. Every time you flush the toilet, the tank refills with fresh water. 

Filling the tank is essential for a powerful flush, but water takes up most of the space inside. Placing a bottle in the tank reduces room for water, which means you will have to flush water several times to clear the mess in the toilet bowl.

A 45-ounce bottle of Fabuloso will take nearly a quarter of the tank, leaving it with a capacity of only 1.2 GPF. That’s not enough for a powerful flush system, especially if you want to keep poop from sticking to your toilet.

Fabuloso Could Impact the Tank Long-Term

One more thing you need to know is that chemicals in Fabuloso may damage the tank in the long run. The high concentration of chemicals can corrode your toilet’s connections, flappers, and flush valve.

The tank consists of sturdy elements such as rubber and plastic, but Fabuloso will damage them in the long run. It’s safe to say that the life expectancy of the standard toilet will decrease if you pour chemicals into the tank.

When the damage occurs, you’ll need to replace these parts. It’s not just about the cost, though – it’s also about time and inconvenience.

Fabuloso Alternatives

Our advice is to avoid cleaners that pose a risk of corroding the tank. You should use different products that are less impactful or specifically designed for cleaning the tank.

For instance, In-Tank Toilet Cleaner Duo-Cubes are safe for toilet components. They can help you with hard water and limescale stains.

Another option is to use a traditional toilet cleaning mix of vinegar and baking soda. Add two-thirds of vinegar and one-third of baking soda to the mix, and it will clean the tank without side effects.

The Bottom Line

Putting a bottle of Fabuloso in the toilet tank is not dangerous, but it’s not good for the overall toilet performance.

It has a couple of negative consequences – it decreases the capacity of the tank and may even damage your toilet’s components in the long run.

We recommend using alternative products designed specifically to clean tank parts. That way, you don’t need to worry about the cleaning efficiency and possible side effects.


Is it safe to put cleaners in the toilet tank?

The general rule of thumb is to avoid putting cleaners in the toilet tank. They contain harsh chemicals that might damage rubber toilet tank parts long-term. However, there are special cleaning products for toilet tanks, and you can use them instead.

What can I put in my toilet tank to make it smell better?

Commercial products that clean toilet tanks typically have a pleasant smell. You can also try dry lemon peels, but make sure they don’t end up in the bowl and clog it. Lemon smells fantastic, and it only contains natural ingredients. 

Can I pour bleach into my toilet tank?

We don’t recommend pouring bleach in the tank and toilet bowl. Like other chemicals, it can also damage parts of the tank. Besides that, bleach cannot break clogs – it will only add to debris if your drain pipes get blocked.
