I'll post separately about how I clean my diffusers at home...but that doesn't necessarily work for my diffuser at my office. It's a small space, and I really don't want it to smell like vinegar for an extended period.
I made this up this morning, and it worked so well! In one of doTERRA's 0.9 ounce (30 mL) spray bottles, I combined 10 drops of Lemon essential oil with a tablespoon of white vinegar. Top off the container with water. Shake well before each use. Spray the different parts of your diffuser and wipe with a soft cloth. So easy!!!
