Here is my version of a clean mouthwash for people who prefer a healthy alternative.
This mouthwash contains only water and three other ingredients. No sugar, No alcohol.

Ingredients:
1 cup filtered or distilled water
3 teaspoons baking soda
2 drops tea tree oil
4 drops peppermint oil

Preparation:
Mix and shake all the ingredients in a glass jar or bottle.
Shake each time before use. Do not swallow mixture.
This is a very refreshing, clean and inexpensive preparation.
