Can You Put Fabuloso in a Humidifier? [Interesting Facts]

Fabuloso is a household name in America. Originated from Venezuela in the 1980s, it soon became one of the most popular all-purpose cleaners in the US. Many people are fascinated by its scent and even try to put it in a humidifier.

Unfortunately, putting Fabuloso in a humidifier is not a good idea, especially when you use it frequently. It can release harmful chemicals that can pose health risks to your health. Moreover, it may cause the malfunction of your humidifier.

This short answer may not be able to convince you. Don’t worry! I will share with you more about Fabuloso in a humidifier in this post.

Why do people want to put Fabuloso in a humidifier?

The scent of Fabuloso is really great, and it can last about 24 hours. The surfaces that are cleaned by it will have a pleasing smell left. Then people start to think about using it as an air fresher naturally.

The air at home can become stale every so often. If we can find something that is affordable and can spread the aroma you like, it would be great, and Fabuloso seems to be just that kind of thing.

I have heard that many people like to boil Fabuloso on the stove to freshen up the whole room. Using a humidifier is similar to boiling water because it also produces mist or vapor, meaning that the scent will be distributed all over the place.

This explains why people want to add Fabuloso to a humidifier.

Can you put Fabuloso in a humidifier? Why?

It is not advisable to use Fabuloso in a humidifier, as I mentioned above. In this section, I elaborate on the possible risks you will run.   

Threat to your health

Fabuloso is a multi-purpose cleanser. It is not meant to be used as an air freshener. Air fresheners are usually safe to inhale because manufacturers have taken the health risks into account.

But as a cleaning product, it often contains some toxic chemicals that are not suitable for inhaling because they will not spread in the air when it is in the liquid state.

Some chemicals will react with each other and produce harmful components when boiled. If you use a warm mist humidifier, things can get even more complicated.

For example, Fabuloso has a component called Glutaraldehyde. Exposure to it can cause burning eyes, difficulty breathing, nasal irritation, lung irritation, and even asthma.

If you have breathing problems, don’t attempt to inhale the vapor mixed with Fabuloso. It can lead to bad consequences you don’t want to get.

It also contains volatile organic compounds (VOCs), leading to headaches, nausea, or other health issues.

If you want to spread aroma through your humidifier, you can add a few drops of perfume or humidifier tablets that manufacturers allow.

Beyond that, it may hurt your pets. Something that is OK for us may be overwhelming or toxic for them. I suggest you give up on this idea if you have furry friends at home.

Damage your humidifier 

The best thing to put in a humidifier is distilled water as the primary purpose, if not the only one, is to improve humidity in the room. The material from which humidifiers are made is also designed to hold water.

When you add Fabuloso to a humidifier, let it stay in the water tank for a long time. It may react with the material of the casing and base and corrode the humidifier parts gradually.

Can you use Fabuloso to clean a humidifier?

White vinegar is the cleanser that is often recommended when it comes to cleaning a humidifier. But it doesn’t mean that other cleaners would not be applicable.

From my own experience, using Fabuloso to clean a humidifier is generally OK. It effectively removes grease, debris, and mineral buildup, which is often seen in the water tank.

You can soak a microfiber cloth in Fabluloso and wipe the machine. I suggest you rinse it off with water if any harmful chemicals are left inside.

Can you put Fabuloso in a diffuser?

Compared to a humidifier, diffusers are not so prone to clogs. Therefore, if you occasionally use Fabuloso as a replacement for essential oil, it may not lead to permanent damage to the machine. 

However, the vapor coming out from it can still do harm to you. The toxic components will get into your airway, triggering short breathing, allergies, or even asthma. Therefore, you’d better not add Fabuloso to a diffuser.

If you insist on using it, you should make sure you stay away from it and only use a small amount of it. 


Fabuloso is a popular cleaning product that is famous for its great scent. It is one of the cheapest cleaners in the market as well. 

Many people use it as an alternative to air refresher by boiling it on the stove or putting it in a humidifier. However, it is not safe to do so.

Some chemicals in Fabuloso are dangerous to be inhaled. They may cause difficulty breathing, lung irritation, sore throat, or even asthma. For those who have breathing problems, you don’t want to put yourself at risk, right?

You should keep in mind that Fabuloso is a cleanser, so the formula is not always inhaling safe. Aside from that, it may damage your machine too. 

If you don’t have vinegar at hand, you can use Fabuloso to clean your humidifier. But you should rinse it with water to remove any residue.
