Dilute! Dilute! OK!* But how much? Here’s a quick reference. None of these soap dilutions are meant to be exact amounts. If what you’re cleaning is really dirty or your water is really hard, then you may want to use more than the specified amount.
That said, these Pure-Castile Liquid Soap dilutions should get you started. You’ll notice that for some applications, we recommend pre-diluting the soap—which usually involved combining the soap with water in a separate container. For other applications, the soap is diluted directly by the water in the shower or faucet. It’s a matter of personal preference.
Keep in mind that if you pre-dilute, you are also diluting the preservative, so the shelf life will decrease. Use the pre-diluted mixture within a couple weeks or mix up in smaller batches. And yes, there are 18+ uses here!
* Long-time Dr. Bronner’s users will remember this expression from the old labels.
