NOTE: Depending on your usage, and the amount
of essential oil you use, you may want to clean the
reservoir and ultrasonic membrane more frequently
for best performance.
For the most thorough clean, pour a 50/50 mixture
of vinegar and water into the reservoir, then soak
for ve minutes. Brush reservoir walls, base, and
ultrasonic membrane clean with a soft-bristle brush
(not included) and rinse. NEVER touch the ultrasonic
membrane with your ngers, as the natural oils in
skin can damage the membrane.
Clean the membrane once every two to three
weeks, depending on your usage.
Clean and dry the unit before extended periods
of inactivity.
