Soap Nuts are the only true non-toxic and sustainable laundry option I’ve found. Homemade laundry soaps are a great alternative to conventional ones, but still create waste products. Soap nuts can be used completely and then composted for a no-waste solution, and a simple re-usable muslin bag is all that is needed to add them to a laundry load!
Another advantage to Soap Nuts is that they are extremely affordable! A handful of Soap Nuts can be purchased at low price and used for multiple loads, making them the most cost-effective laundry solution I’ve found too. Since they are no-suds, they are great for front loader and HE machines and they don’t leave residue. They are also cloth diaper safe!
They don’t have the rain fresh smell of commercial detergents, but I like the light apple scent (that disappears when clothes dry).
How to user soap nuts for laundry
To use, put 4-6 Soap Nuts in a muslin bag that is included and place in washer. Wash as usual with cold, warm or hot water. After washing, remove bag and let dry. Dry clothes as usual. Soap Nuts may be re-used several times until the shells start to become soft and grey, and then they should be composted"
