For those lingering smells or spots/marks on your clothing add a ½ cup of Borax to your wash. It is safe to use with your balls! (for more info on Laundry Balls go to http://www.laundrydivas.com) Borax is a naturally occurring mineral widely used as a laundry detergent booster. Also known as sodium borate, this white powder is not harmful to washing machines, plumbing pipes or septic tanks, and is non-toxic when used in recommended amounts.
Borax is considered environmentally friendly because it’s a natural product that does not contain phosphates or chlorine.
