I like to do this about once every two months…
You will be surprised at how much build up can get in there - especially if you use thicker oils and you will be delighted at the powerful mist you see streaming out of your newly cleaned diffuser!!
How to Clean Your Diffuser:
Turn off the diffuser
Fill the reservoir halfway with clean water
Add 2 TBSP of white vinegar to the water
Turn on the diffuser and run for 5 minutes
Drain reservoir
Dip a cotton swab in vinegar or rubbing alcohol and wipe out the reservoir, lid and mist chip
Rinse reservoir with water and let air dry
You can also make a spritz bottle of 1 part vinegar + 1 part water to spray in the diffuser and wipe out as needed.
