Question: how to clean zaq diffuser?
Answer: Turn off and unplug the diffuser.
Fill the water tank about half way with clean water (stop well before the max line).
Add 10 drops of pure white vinegar.
Plug it in and turn it on.
Let it run for about 3 – 5 minutes so the vinegar will disperse through the whole unit.
Turn off and unplug the diffuser.
