Here’s How to Clean An Essential Oil Diffuser

Essential oil diffusers are amazing inventions that disperse the aroma of relaxing and even therapeutic essential oils, but they do require maintenance and regular cleaning to work at their best. Failure to keep your essential oil diffuser clean can cause it to malfunction or even stop working altogether. Here are some simple steps that guide you through the process of how to clean your essential oil diffuser and keep it maintained for the best possible performance.

Why it’s important to clean your essential oil diffuser regularly

Some essential oils, although smell wonderful, have a residue that can interfere with the aroma of the next oil type that you choose. It takes a good cleaning to remove the residual oils so you get a clean pure scent during each use. In addition, some of the essential oils available can be corrosive to the materials of the diffuser if they are left inside for long periods of time. These are the main reasons why it’s so important to keep your diffuser clean and maintained.

Quick cleaning method

There are two ways to give your diffuser a quick cleaning in between uses. This removes the majority of the residual oils and gives you a fresh start for the next batch. The first method is to wipe the diffuser out after use and then let it dry before you use it again. You can also run a batch of lemon oil through the diffuser to make it easier to clean out before wiping down. Just be sure that you rinse out the nozzle with clean water then wipe it dry in between uses.

  • Step 1: Read the manual – Since there are a variety of different brands and models, it’s always a good idea to read the manual that comes with your diffuser. If you don’t have a manual, the odds are high of finding the information online. Some manufacturers have specific cleaning methods that they recommend, along with tips for maintenance. If you can’t find the manual online then here are some standard cleaning methods that work for most essential oil diffusers.
  • Step 2: Unplug your diffuser – You should always unplug your essential oil diffuser before attempting to clean it. Removing the electrical source is vital for protecting yourself from accidental electrocution.
  • Step 3: Gather the supplies you will need – There are very few items that are needed to perform the steps involved in cleaning an essential oil diffuser. They are clean water, pure white vinegar cotton swab, and a clean dry cloth.
  • Step 4: Fill the diffuser halfway with water – Fill your diffuser with clean water but be careful to only fill the unit to the halfway mark.
  • Step 5: Add white vinegar – Next, place about 10 drops of white vinegar into the water that is in the diffuser. This is useful for loosening and removing the oils that may be stubborn and stick to the various components of the diffuser.
  • Step 6: Run the diffuser – Now you’re ready to plug the diffuser in and turn it on. Allow the diffuser to run for approximately 5 minutes. This makes sure that the water and white vinegar solution gets through every working part to loosen and remove oils.
  • Step 7: Drain the diffuser – Next, it’s time to completely drain the diffuser. Make sure that all of the water and vinegar solution that you can remove is drained from the unit.
  • Step 8: Swab the corners – Take a cotton swab and either dip it in vinegar or orange essential oil to clean out the corners and the tight spots in the diffuser. It’s important to do this step to make sure that the residual oils that are stuck in hard to reach spots are removed.
  • Step 9: Rinse the diffuser – The next step is to rinse the diffuser out with clean clear water. This will remove any leftover vinegar and water solution and also any stubborn essential oils that have collected. Empty the diffuser or the clean water.
  • Step 10: Dry the diffuser – The last step is to wipe down the diffuser with a clean dry cloth to dry it. You can also use cotton swabs to dry the tight areas of the diffuser and the corners.

Important tips

One of the reasons why it is so important to read the user manual that came with your diffuser is because some manufacturers will void the warranty if you clean it with vinegar. If there is a warranty that is still in force on your unit, it is best to follow the manufacturer’s specific instructions or call the customer service number provided in the manual for further directions.

Keeping your diffuser maintained

Always remember to clean your essential oil diffuser with a quick cleaning method after each use. The reason for this is because if you fail to do so, and the unit stops working, your warranty might be voided for lack of proper maintenance. Leaving essential oils in a diffuser for long periods of time can cause excessive wear and tear on the unit that reduces its lifespan. You don’t have to complete the 10 steps deep cleaning method every time you use the diffuser. That is why we provided quick cleaning tips for you to do after each use. It just takes a few minutes and it can save you a lot of hassle in the long run.


It’s not difficult to clean an essential oil diffuser. These units require a few simple steps that will help them to last longer and perform better over time.
