Fill a foaming hand soap container 1/4 of the way with Castile soap. Add 10-20 drops lemon essential oil. Fill the rest of the way with water.
That's it!
Notes
Castile soap is a super pure product made only of saponified oils. Traditional castile soap is olive oil based, but Dr. Bronner’s adds other vegetable oils including coconut. It does not contain chemicals, like triclosan, that are gut damaging and endocrine disrupting.
Lemon essential oil has natural antibacterial and antifungal properties. It is also a very powerful cleanser and has a fresh scent. Best of all, it is the cheapest essential oil on the market. I buy only Certified Pure Therapeutic Grade oils from DoTerra, and a whole bottle is still only 10 bucks.
Now, of course, you can customize this recipe for other scents. Try adding wild orange for a bright and zesty scent. Use lavender in a wash for baby. Add OnGuard or Thieves during flu season for added immune support. Melaleuca combined with lemon would make an excellent cleaning solution.
