Organic soap nuts (although not actually a nut and also referred to as soap berries) are a natural, multipurpose, hypoallergenic, grey water safe, palm oil free, plastic free, cost effective household cleaning solution that works!
To add some natural fragrance to your laundry load, you can add essential oils such as the That Red House Laundry Tonics. For tough stains, add some Sodium Percarbonate (Oxygen Bleach) to your wash load along with the soap nuts.
