Soapnuts are the eco-friendly alternative to plastic bottles with chemical soaps. They are completely biodegradable and are suitable for people with allergies or a sensitive skin. When you use soapnuts, you don't even need fabric softener anymore.
How to use?
Take 4 to 6 soapnuts, put them in a small soapnutbag and knot it closed tightly. Put it in the washin machine along with your laundry. Afterwards, just take the bag out of the machine again.
If you wash at 90°, you can use the soapnuts once. If you wash at a lower temperature, like 30° to 50°, you can easily reuse the same bag of soapnuts about three times.
