Remove the inner glass container, and add about 5 drops of OnGuard and 3 drops of Peppermint. Fill with regular tap water. BOOM! Anti-bac spray to go! You can also use a couple spritzes to get rid of coffee breath.
Use these for ANY oils you'd like to take with you. How's about a Peppermint spritz when you're hot or feeling a headache coming on? Put some Bergamot & Black Pepper in for an uplifting, bright scent. Make sure to dilute with water.
