- Empty/clean foaming pump container
- Thieves Oil
- Castle Soap (We like Dr. Bronners)
I fill the container with water about 2.5" from the top. I added about 2-3 tablespoons of castle soap then 5 drops of Thieves oil. You're done! Now you have not only an inexpensive natural soap, but adding Thieves oil makes it antiviral, antibacterial, and antifungal!
