Dilute! Dilute! OK!* But how much? Here is a quick reference. None of this is a hard and fast rule. If your stuff is really dirty or your water is really hard, then you may want to use more than the recommended amount. However, this should get you started. You’ll notice that for some applications, I recommend pre-diluting the soap – combining the soap with water in a container. For other applications, the soap is diluted by the water present in the situation. It’s a matter of personal preference. Keep in mind that if you predilute, you are also diluting the preservative (tocopherols – vitamin E), so the shelf life drops. Use within a couple weeks. And yes, there are 18 uses here.

Face: 2-3 drops on wet hands, applied to wet face

Hair: ½ Tbsp. in your hand, worked into wet hair, or dilute ½ Tbsp. in ½ a cup of water and work that into wet hair

Bath: Completely depends upon water amount, but roughly 2 Tbsp. soap in an average sized tub. (Doesn’t bubble, but still cleans)

Clearing Congestion: 1 Tbsp. in a bowl of steamy hot water. Breathe in mist with a towel draped over the head.

Household uses:

Dishes (handwashing): Pre-dilute 1:10 with water. Squirt on a scrub brush and scrub dishes.

Laundry: 1/3-1/2 c. of soap for a large load in a normal washer. Add ½ c. vinegar to the rinse cycle. Use half of these amounts for HE

Mopping: ½ c. of soap in 3 gallons of hot water

All-purpose cleaning: ¼ c. soap in a quart of water in a spray bottle. Add ¼ tsp. tea tree essential oil if desired.

Windows: 1 Tbsp. soap in a quart of water in a spray bottle. Follow up with pure club soda, or half vinegar/ half water.

Other Uses:

Fruit and Veggie Rinse: 1 dash (approx.. ¼ tsp.) in a bowl of water. Dunk produce and swish. Then rinse in clear water.

Dog washing: Amount varies widely depending on size, hair type and length, and overall dirtiness. I wet my dog thoroughly, then start to work in castile soap up and down their body until I have a good lather. Really massage it in down to the skin. Your dog will thank you for it.

Plant spray for bugs: 1 Tbsp. in a quart of water. Add ½ tsp. cayenne pepper or cinnamon, if desired.

Ant spray (not on plants): ¼ c. tea tree soap in a quart of water. (This concentration will burn plants.)
