One cube is perfect for one load of laundry, one load of dishes, or one mop of the whole floor. I also fill my small plastic shampoo bottle (an old ketchup dispenser with a tiny nozzle that I got at Walmart for .98 cents works perfect!) and keep it in the shower. Fill the dishwasher soap dispenser with soap nuts liquid.
Technically a berry, soap nuts are lauded as one of the best environmentally conscious alternatives to chemical detergents and soaps. A highly prolific tree that can grow well in degraded environments, soap nut trees are considered by some to be a viable solution to global deforestation. And their cleaning potential? It’s considered almost limitless.
