How to Clean Your Diffuser
There seems to be a lot of mystery and angst surrounding how exactly to clean your diffuser when in reality it's quite simple. I clean my diffuser out every couple of months unless I see visible build up or smells seem to linger inside it.
To make things easier for you I recorded a short video explaining my process.
Caution: Make sure when you wipe down your diffuser you are careful to be gentle around the ultrasonic atomization piece at the bottom of the interior of your diffuser. It looks like a little circular piece typically with a silver ring around it. You don't want to damage it by pressing too hard.
If you find that a simple wipe down doesn't do the trick you can also run your diffuser with water and a small amount of white vinegar (a tablespoon or so is fine), much like you would clean a coffee pot, but I haven't really found that to be necessary myself.
