Additional Details ------------------------------ Product description: We've discovered a whole new clean that reduces soaps and petrochemicals in the Earth's water supply and helps alleviate allergies and skin irritations. Simply add the detergent-free Wonder Ball to laundry (pre-treat any stains) and a small amount of detergent (or none), and a proprietary blend of minerals and magnetics within the ball lowers the water's surface tension, making it "wetter" so it can clean fabric fibers more deeply. 2"; 5 oz. Washing laundry with the Wonder Ball only and no laundry soap also eliminates the detergent residue that aggravates allergies and irritates skin. Imported. Lasts about two years or 2,000 washes. Do not use in the dryer. Can use to hand wash delicates. Use with top- or front-loading washing machines. Works in hard or soft water.
