Cleaning your essential oil diffuser is an important step in prolonging its lifespan and ensuring optimal performance. To begin, carefully unplug the diffuser and empty any remaining water from the reservoir. Next, remove the cover or lid and wipe it down with a mild detergent or vinegar solution. Rinse thoroughly and allow it to air dry before reassembling.

Now, it’s time to tackle the interior. Using a cotton swab dipped in rubbing alcohol, gently clean the ultrasonic plate or any other accessible parts. Be cautious not to apply excessive pressure to avoid damaging the delicate components. Once finished, wipe away any residue with a clean cloth.

The diffuser’s plastic or glass reservoir should also be cleaned regularly. Start by filling it halfway with warm water and adding a few drops of mild dish soap. Swirl the soapy water around and let it sit for about 10 minutes. Then, empty the reservoir and rinse it thoroughly to remove all traces of soap.

For stubborn oil residue, a mixture of vinegar and water can work wonders. Fill the reservoir halfway with equal parts vinegar and water, let it sit for 10-15 minutes, then empty and rinse thoroughly. Remember to always refer to your specific diffuser’s instructions for additional cleaning tips and precautions. By following these simple steps, your essential oil diffuser will stay clean and in great working condition for years to come. Happy diffusing!
