Maintenance
Regular cleaning is essential for optimal performance and longevity of your diffuser.
Cleaning Instructions:
- Unplug and Empty: Always unplug the diffuser from the power outlet and empty any remaining water from the tank.
- Wipe the Tank: Use a soft cloth or cotton swab with a small amount of mild dish soap to gently wipe the inside of the water tank.
- Clean the Ultrasonic Plate: Carefully clean the ultrasonic vibrating plate (the small disc at the bottom of the tank) with a cotton swab dipped in white vinegar. Do not scrub or use abrasive materials.
- Rinse and Dry: Rinse the tank thoroughly with clean water, ensuring no soap residue remains. Wipe the exterior with a dry cloth.
- Air Dry: Allow all parts to air dry completely before reassembling or storing.
Important Notes:
