An ultrasonic aroma diffuser from Stockholm Fragrance uses advanced ultrasonic technology to disperse a fine, fragrant mist of water and essential oils, creating a luxurious atmosphere throughout your space. Once you experience it, there’s no turning back.
But to keep your Aroma Diffuser performing at its best—and to enjoy long-term, reliable use—it’s important to clean it regularly. Fragrance oils and essential oils are highly concentrated, and if not cleaned properly, residue can build up and affect the performance or lifespan of your diffuser.
In this guide, we’ll walk you through how to clean your Stockholm Fragrance Aroma Diffuser in 8 simple steps, plus share expert tips on maintenance and troubleshooting.
Why Regular Cleaning Is Important
The entire water tank of your ultrasonic diffuser is a sensitive electronic component. Over time, concentrated oils can leave residues on the ceramic plate (ultrasonic chip) at the bottom of the tank. Without proper care, this buildup can damage the diffuser, reduce mist output, and shorten the unit’s lifespan.
To avoid this, we recommend doing a light cleaning once a week, and a deep cleaning once a month.
How to Clean Your Aroma Diffuser in 8 Simple Steps
Important: Never clean your diffuser under running water. Most ultrasonic diffusers have an air outlet located on the rim of the water base. If water enters this opening, it can reach the circuit board and cause permanent damage.
-
Unplug your diffuser from the power source before cleaning.
-
Avoid running water directly into the base. Always pour water using a jug, and keep it away from the air outlet.
-
Use a damp cloth to gently wipe the inside of the water tank.
-
Clean the ceramic ultrasonic plate at the bottom with a moistened cotton swab or soft cloth.
-
Perform a deep clean once a month:
-
Fill the tank halfway with water.
-
Add 1–2 teaspoons of white vinegar.
-
Turn on the diffuser and let it run for 5–10 minutes.
-
Turn it off, pour out the solution, and rinse thoroughly.
-
-
Wipe the unit dry with a microfiber cloth.
-
Clean the outer glass or cover (such as the glass dome on Stockholm Fragrance’s egg-shaped diffusers) with a mild detergent. This part is water-safe but should be dried completely before reassembling.
-
Always add water first, then oil. Pour water on the opposite side of the air outlet, and only then add the fragrance oil. Adding oil first can damage the ceramic plate if it sits directly on the surface.
Care Tips for a Longer Lifespan
All Stockholm Fragrance Aroma Diffusers have an estimated lifespan of around 2,000 hours of use. However, with regular care, many customers find their diffuser lasts far longer.
-
Clean the diffuser weekly to remove oil buildup.
-
Instruct all household or office users on how to refill and clean the unit properly.
-
Avoid leaving standing water in the tank for prolonged periods.
By following these simple habits, you’ll enjoy stronger mist, cleaner diffusion, and long-term performance.
Troubleshooting Common Issues
-
Reduced Mist Output: This often indicates a buildup on the ceramic plate. Try a deep cleaning cycle with vinegar as described above.
-
Strange Odor or Color in Mist: This may be due to residual oils. Clean the water tank thoroughly and let it air dry.
-
Unit Not Powering On: Check all cables, ensure the air outlet hasn’t been splashed, and refer to your user manual.
Remember, all essential oils, fragrance oils, and perfume oils are highly concentrated. If left to sit in the diffuser without cleaning, they can break down seals and electronic components beneath the ceramic plate.
Final Thoughts
Proper maintenance of your Stockholm Fragrance Aroma Diffuser ensures not only beautiful fragrance but also longevity and performance. Take a few moments each week to clean your diffuser, and once a month for a deeper refresh—it’s a small ritual that keeps your home smelling extraordinary and your diffuser working like new.
For specific care instructions, always refer to the user manual included with your diffuser model.
