Hard water is a problem for laundry. you know it when you have it: stiff, stained and even smelly clothes. Normal laundry boosters can leave a dingy, stiff and irritating residue on your clothes.
Certain phosphates can safely eliminate these problems and be environmentally friendly. They become a problem only with overuse.
Charlie's Soap Laundry Booster and Hard Water Treatment uses a biodegradable phosphate that leaves no residue on your clothes while softening your wash water.
Use this booster when you have trouble with hard water or difficult stains. Keep your clothes and the environment clean.
