In a mason jar, add the water first (to prevent bubbles) then the liquid castile soap, followed by the essential oils.
Top your mason jar with a rust proof soap pump.
Shake the ingredients together.
Shake the soap dispenser before using, and then squirt a small amount on your hands as needed, rinsing with water.
Notes
This makes a great DIY gift idea and it is super fun to get the kids involved. It makes washing hands so much more fun when they know they made it themselves.
