Can I re-use SoapNuts?
Reuse SoapNuts 4-6x in the washing machine and then dispose of them in your compost bin. You will find that you will get more washes when using cold water. Hot water washes (up to 40 degrees) release more saponin and the wash bag will need to be reloaded with fresh SoapNuts more often. I find that I get 2-3 wash loads when using warm water. The SoapNuts look shiny and fleshy when they have released their saponin.
