A little tree fruit called the soapnut is full of a soapy detergent-like substance called saponins. They come dried, and when you soak them in water, they release saponins. Bubbles and suds appear from the soap nuts to clean just about anything you want.
You can make a soapy liquid from boiling soapnuts in water. This mild detergent can be used for laundry, dishwashing, or even soap and shampoo.
Boil 12-15 whole soapnuts in 6 cups of water for 30 minutes. You should be left with 4 cups of soapnuts liquid, a concentrated chemical-free detergent. You can compost the leftover soapnuts shells.
In liquid form, soapnuts can clean just about anything. You can use it for soap or shampoo, and even as a multipurpose or window cleaner.
