Some wander this Earth seeking wisdom. A lot of folks Charlie talks with are looking to beat hard water. Our Booster is a hard-water treatment made from a non-toxic biodegradable phosphate that brings out the best of Charlie’s Soap without leaving any residues on your clothes. It controls minerals in your wash water with just 1/2 tablespoon per load. Your septic system and washing machine will be safe, too, because Booster is completely soluble.
