Move&Wash laundry nuts are the fruits of the Sapindus Mukorossi tree, a 100% natural and biodegradable detergent that will not pollute rivers or seas after use. Certified India Organic and USDA Organic, it's a safe cleaning product, specifically for baby clothes or those with allergies. In addition, laundry nuts contain saponin, a soap that naturally cleans and softens clothes. No fabric softener is required. Plastic-free washes with certified high quality. With one 250g box of walnuts you can make 60 washes. It's recommended to break 3-4 walnuts into pieces, place them in one of the two reusable bags, and close them with the drawstring. Place the bag in the washing machine drum at a temperature of 30°C or higher (this creates the natural soap). After the wash cycle is complete, remove the bag and let it dry (not in the sun). Reuse a maximum of 3 times. Store in a cool, dry place.
