To take the time to make certain cleansing or personal products at home can be experiments in themselves. I find some are not worth the time or effort, but this homemade mouthwash is easy to make with simple ingredients and works great.
Mouthwash:
1 cup filtered water
1/2 teaspoon sea salt
2 teaspoons baking soda
7 drops of liquid stevia
5 drops of peppermint oil
5 drops of clove oil
1/8 teaspoon vanilla
I just mix all ingredients together with a whisk until dissolved and then funnel it into a pretty jar to set on my bathroom counter. (If your water is cold you may consider warming it before adding the salt so it will dissolve better.)
