A scent diffuser can give your home a pleasant scent, but it needs regular cleaning. Rinse the aroma diffuser thoroughly after each use and deep clean once a month. Proper cleaning of the diffuser will prevent dirt from accumulating in the diffuser.
Steps
Method 1 of 3: Cleaning the Diffuser After Use

Step 1. Pour the remaining water into the sink
Pour water through the rear valve to avoid accidentally flooding the diffuser control buttons and thus causing it to break.

Step 2. Wipe the inside and outside of the diffuser
Apply some natural dish soap to a cotton brush. Gently wipe the reservoir and the outside of the diffuser.
Use only natural cleaning products without any chemical additives. Harsh chemicals can damage the diffuser

Step 3. Wash the diffuser with a cloth dampened with clean water
Wipe the inside of the reservoir and the outside of the diffuser to rinse out any remaining detergent. Wipe the diffuser with a clean cloth until the water running off it is clear.

Step 4. Clean the spray chip
There should be a small ultrasonic chip inside the water tank. If you are unsure of where it is located in your diffuser, check your instruction manual. Wipe the microcircuit with a cotton pad moistened with rubbing alcohol.
Method 2 of 3: Deep cleaning the diffuser

Step 1. Fill the diffuser with water
Use clean tap water at room temperature. Fill the reservoir to about half full.

Step 2. Add 10 drops of white vinegar
White vinegar will cleanse, disinfect, and break down any oils trapped inside the diffuser. Add about 10 drops of white vinegar to the reservoir.
Use only pure white vinegar. Do not clean the diffuser with liquids containing chemical additives

Step 3. Run the diffuser for 10-15 minutes
Plug the diffuser into a power outlet and start it. Let it run for 10-15 minutes to dissolve any oils that may have remained on the sides of the diffuser.

Step 4. Pour out the water
Switch off the diffuser, unplug it and drain the water from the reservoir into a sink.

Step 5. Wipe the inside of the diffuser
Wipe the diffuser reservoir with a soft cloth, cotton pad, or small brush. Be sure to remove any dirt adhering to the sides of the tank as it can dilute odors while the diffuser is operating.
Be sure to wipe off any dirt from the spray chip. The accumulation of dirt on it can lead to incorrect operation of the diffuser

Step 6. Wipe the outside of the diffuser
Once you've finished cleaning the interior, take a soft cloth, cotton ball, or a brush dampened with water and wipe off any dirt, debris, and fingerprints on the diffuser.
Do not let water come into contact with buttons or under the device
Method 3 of 3: Common mistakes and how to avoid them

Step 1. Read the manufacturer's documentation
Most diffusers can be safely cleaned using the above methods. However, different diffusers have different designs. Your specific diffuser may have specific cleaning instructions.

Step 2. Discard water and oil after each use
The longer the water and oil stays in the diffuser, the more difficult it will be to clean. Pour out any remaining water or oil each time you clean the diffuser. Thanks to this, you do not have to spend a lot of time cleaning it.

Step 3. Unplug and empty the diffuser before cleaning
Do not start cleaning the diffuser until you unplug it from the wall outlet. Unplug the diffuser before each cleaning. If there is water or oil in the diffuser, drain it before cleaning.
