5. Maintenance

5.1 Regular Cleaning

To ensure optimal performance and longevity, clean the diffuser regularly, especially if changing essential oils or after 5-6 uses.

Unplug the diffuser from the power outlet.
Remove the top cover.
Carefully pour out any remaining water from the 'Drain Side' of the tank to avoid water entering the air outlet.
Wipe the inside of the water tank with a soft cloth or cotton swab. For stubborn residue, use a small amount of white vinegar or rubbing alcohol, then rinse thoroughly with clean water.
Clean the ultrasonic disc (the small ceramic disc at the bottom of the tank) gently with a cotton swab. Do not scrub or use harsh tools, as this can damage the disc.
Wipe the exterior of the diffuser with a soft, damp cloth.
Allow all parts to air dry completely before reassembling or storing.

5.2 Storage

When not in use for an extended period, ensure the diffuser is clean and dry. Store it in a cool, dry place, away from direct sunlight and extreme temperatures.
