The wash nuts are actually the fruit of a tree, called Sapindus Mukorossi, which means "soap tree". This tree grows mainly in India and Nepal, where its nuts are harvested, dried and then pitted in order to be usable and marketed.
They have the main property of containing saponin, a natural surfactant, which is released in contact with water. This detergent will allow, among other things, to do laundry as the Indians have traditionally done for centuries!
Washing nuts are all natural, and they make it possible to produce eco-friendly detergents, unlike chemical detergents. In addition, they are 100% biodegradable.
Instructions: (printed on the back of the bag)
Put in one of the two small bags provided 8 to 10 halves of nuts.
Close the bag and place it directly in the drum of the washing machine or in the cutlery basket of the dishwasher.
The same nuts can be reused up to 3 times for a laundry at 30 °, 2 ° to 40 °, 1 or 2 ° to 60 ° and 1 to 90 ° depending on the size of the nuts and their saponin content which may vary according to crop .
Make sure that the packet containing the nuts, placed in the center of the drum, can circulate freely in the linen and thus release the saponin optimally.
