- 2/3 cup baking soda
- 4 tsp fine sea salt (optional – gives paste extra scrubbing power, but is okay to leave out if the taste is too salty)
- 1 – 2 tsp peppermint extract according to taste (or add your favorite flavor – spearmint, cinnamon, orange, etc.)
- water (add to desired consistency)
- Mix all together in a container that has a lid. Cover.
