Our biodegradable booster and hard water treatment is made from an environmentally friendly phosphate that brings out the best in Charlie's Soap detergents. Without leaving any residue on your clothes or in your washing machine, it controls minerals in your wash water with just 1/2 tablespoon per load. Your septic system and washing machine will also be safe because our booster is completely soluble. Hard water does not pose a health risk, but it can cause scale mineral build-up in pipes and plumbing fixtures that reduces the effectiveness of laundry soap. Charlie's Soap booster is a non-toxic, biodegradable phosphate that can safely eliminate problems associated with hard water all while remaining environmentally friendly.
