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 Dr. Bronner’s Castile 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.
* Long time Dr. Bronner’s users will remember this expression from the old labels.
Face: 2-3 drops on wet hands, applied to wet face.
Body: One small squirt on a wet washcloth, applied to a wet body.
Hair: ½ Tbsp. (7.5 mL) in your hand, worked into wet hair, or dilute ½ Tbsp. (7.5 mL) in a ½ cup (120 mL) of water and work that into wet hair. Follow with Dr. Bronner’s Citrus Organic Hair Rinse or diluted apple cider vinegar.
Bath: Completely depends upon water amount, but roughly 2 Tbsp. (30 mL) soap in an average sized tub. (Doesn’t bubble, but still cleans.)
Shaving: Face – 10 drops; Underarms – 3 drops; Legs – ½ tsp (2.5 mL); Work to a lather in wet hands and then apply to area.
Teeth: 1 drop on a toothbrush. (Yes, it tastes like soap.)
Foot Bath: 1 ½ tsp. (7.5 mL) in a small tub of hot water.
Clearing Congestion: 1 Tbsp. (15 mL) Peppermint or Eucalyptus Castile soap in a bowl of steamy hot water. Breathe in mist with a towel draped over the head.
Dishes (Handwashing): Pre-dilute 1:10 with water. Squirt on a scrub brush and scrub dishes.
Laundry: 1/3-1/2 c. (80-120 mL) of soap for a large load in a normal washer. Add ½ c. (120 mL) vinegar to the rinse cycle. For whites or extra grimy loads, add ½ c. (120 mL) baking soda to the wash cycle (optional). Use half of these amounts for HE.
Handwashing Delicates: Add 1 capful Dr. Bronner’s Liquid Castile Soap to cold water. Swish gently. Let soak 10 minutes. Swish again to release loosened grime. Rinse with clean water. Gently press out excess water with a towel. Hang or lay clothing flat to dry.
Mopping: ½ c. (120 mL) of soap in 3 gallons (12 L) of hot water
All-Purpose Cleaning Spray: ¼ c. (60 mL) soap in a quart (1 L) of water in a spray bottle. Add ¼ tsp. (1.25 mL) tea tree essential oil if desired.
Windows: 1 Tbsp. (15 mL) soap in a quart of water in a spray bottle. Follow up with pure club soda, or half vinegar/ half water.
Toilet: Predilute 1:4 with water in a squirt bottle. Add ¼ tsp. (1.25 mL) tea tree oil. Empty toilet, squirt bowl thoroughly, sprinkle baking soda on the brush, scrub bowl, let sit 10 minutes, turn water on, flush.
Fruit and Veggie Rinse: 1 dash (approx. ¼ tsp.) in a bowl of water. Dunk produce and swish. Then rinse in clear water.
Cleaning Makeup Brushes: Wet the make-up brushes in water. Add 1-2 drops of Castile soap right on to the bristles. Massage in gently for 10+ seconds, then rinse. Repeat cleaning as needed until water runs clear.
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. (15 mL) in a quart (1 L) of water. Add ½ tsp. (1.25 mL) cayenne pepper or cinnamon, if desired. Spray plants twice daily in the cool of the day until infestation clears.
Ant Spray (not on plants): ¼ c. (60 mL) Tea Tree Castile Soap in a quart (1 L) of water. (This concentration will burn plants.)
I’ve tried to keep this short and sweet. If you have any questions, please ask away!
