The addition of 80 proof vodka (or other 80 proof liquor) to the Essential Oil Mouthwash formula will increase the cleansing action and preserve the mouthwash so you can bottle and travel with it or store it for future use. More essential oil is used in this formula as well. If you like the results, make a larger batch by multiplying the ingredients.
2 oz. water 1/2 teaspoon baking soda or salt
6 drops tea tree oil 2 oz. 80 proof vodka
6 drops peppermint essential oil
Place ingredients in a jar and cap with a tight-fitting lid. Shake well before each use. Makes 4 oz.
Variation: The peppermint in the previous formula can be replaced by cinnamon, fennel, anise, spearmint, grapefruit or other essential oil of choice.
