How To Clean A Diffuser For Essential Oils

It can become quite the pain if you have to clean your essential oil diffuser every time you wish to change the scent inside. And sometimes if you wait too long it can become clogged with old oil. 

However, you must clean essential oil diffusers regularly to maintain their function.

Keep reading to learn how you can clean your essential oil diffuser to keep your aromatherapy machine in good health and get the most out of this investment.


What Is An Essential Oil Diffuser?

An essential oil diffuser is an appliance that resembles a mist air humidifier and facilitates aromatherapy, a holistic healing practice that dates back over 6000 years. What makes the diffuser different from the humidifier is that in addition to adding moisture to the air, which can help with breathing and skin conditions, the diffuser creates a pleasant scent while adding the health benefits one can gain from aromatherapy oils.

The diffuser breaks down essential oils into smaller molecules which are then dispersed into the air to create a pleasant and calming smell in the surrounding area. Different essential oils have different effects and purposes, meaning that the impact of the oils depends on which kind you are using.


How To Clean Your Essential Oil Diffuser?

It is important to clean your essential oil diffuser in order to prevent clogging and keep the diffuser from breaking. Besides function, clean your essential oil diffuser often to switch scents without the old scent lingering on.


To clean your diffuser and get rid of essential oil residue, you will need the following supplies:

  • Dishwasher detergent
  • Rubbing alcohol
  • Water


You will also need the following tools to help you clean your diffuser:

  • Microfibre or soft cotton cloth
  • Cotton swab


Once you have these supplies and tools, you will clean your diffuser. You should take the following steps:

1. Unplug Your Diffuser

Your diffuser is an electrical appliance and should be unplugged before cleaning to prevent the risk of electrocution.

2. Empty And Clean The Water Reservoir

Once your diffuser is safely unplugged, you can pour out the remaining oil and water in the diffuser's water reservoir. Water left stagnant for long periods can become dangerous for your health due to mold and mildew growth.

Once you have emptied the reservoir, apply a minuscule amount of dishwasher detergent to your microfibre cloth and use it to wipe the inside of the water reservoir. Then, proceed to rinse it out.

3. Clean The Ultrasonic Plate Or Chip

The ultrasonic plate/chip is the part of the diffuser that breaks down your essential oils into smaller molecules to distribute into the air. This plate causes ultrasonic vibrations that then create your essential oil mist.

To keep this critical part of your diffuser working correctly, you must clean it. You can do this by using a cotton swab dipped in rubbing alcohol to gently wipe down the plate to remove any essential oil residue.

4. Reassemble The Diffuser

Once you have finished cleaning, you can then reassemble the diffuser. Now, it will be ready to refill with water and your next aromatherapy scent choice.


How To Deep Clean Your Essential Oil Diffuser?

If you plan to make your diffuser last, you need to deep clean it to get the tight spots and ensure that it is immaculate. This process should be done at least once a month for optimum functioning.


To deep clean your diffuser, you will need:

  • Water
  • Distilled white vinegar
  • Rubbing alcohol


Some tools that will help you with the cleaning process are:

  • A soft cloth or paper towel
  • A cotton swab


The steps you must take to perform a deep clean of your diffuser are:

1. Empty Any Standing Water

You should empty the standing water from your diffuser before performing a deep clean so that there are no essential oils or excess water left inside. Remember not to get any external parts of the diffuser wet during the cleaning process.

2. Fill The Diffuser With Your Cleaning Solution

Fill your diffuser around halfway to the fill line with clean water, making sure to stop before the max line. Then, take your distilled white vinegar and add a small amount, around 10 drops. The vinegar assists in removing and dissolving any oils stuck on the glass or plastic inside the diffuser.

3. Run The Diffuser

You should run the diffuser for around 5 minutes, ensuring that the mixture reaches all small and hard-to-reach places in the diffuser.

4. Unplug And Empty The Reservoir

Once the mixture of pure white vinegar and water has dispersed throughout the diffuser, you should unplug it and empty the reservoir.

5. Clean The Ultrasonic Chip

Now that the diffuser is empty, you should take a cotton swab doused with vinegar and thoroughly wipe down the ultrasonic plate. Then, Rinse the reservoir with water to remove the vinegar smell before thoroughly drying all excess water with a soft cloth. Then, you should be good to go.


How Often Should You Clean Your Essential Oil Diffuser?

You should clean your diffuser briefly every time you change oils and between uses. You should perform a deep cleaning on your diffuser once a month to ensure that there is no debris and to prevent any blockages.

If you invest time into cleaning your diffuser, it will perform better. If you don't, it will not function at its peak capacity, and you run the risk of accidentally mixing aromas. If your diffuser comes with a cleaning manual, this should be followed. If there is no manual, you can use the advice you find online.
