An eco‒friendly alternative to laundry detergent, all‒natural Laundry Soap Nuts. From the Sapindus Mukorossi tree, which is native to Nepal and India, come these naturally‒cleansing nuts. Simply use 2‒3 nuts in a small cotton bag when washing with hot water and 4‒5 nuts in cold water. Gentle on skin, great for baby clothes.
