Chlorine bleach is harsh. It works – at the price of damaging certain fabrics. Charlie’s Soap Oxygen Bleach is different. It is formulated from washing soda and hydrogen peroxide, which whitens whites and tackles stains and odors while being safer for the environment, including your septic tank. As little as two tablespoons per load will do the trick. It is color safe, but be sure to follow garment care instructions.
