Recently I have rediscovered soap nuts. I have used ready-made soap nut liquid before as a laundry detergent but this is the first time that I made my own from scratch! So basically all you need is whole soap nuts, water and some essential oil of your choice (optional).
Bring 3 cups of water to boil, add about 10 full nuts to the boiling water (it’s better to break them into smaller pieces first) and boil on a medium heat for about 30 minutes. Then set aside and leave the liquid to cool.
Strain away the nut shells and pour into a container of your choice, then add the essential oil if using.
Note that the soap nut liquid will be more watery than your regular dishwashing liquid and laundry detergent and not as foamy so it takes time to get used to it. At first I used way more of the liquid than was necessary but once you master it you’ll see that it works just as fine : )
