Biodegradable Booster & Hard Water Treatment

Boosts cleaning power of your detergent by controlling hard water.

Our biodegradable booster and hard water treatment is made from an environmentally friendly posphate 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 biodegradable phosphate that can safely eliminate problems associated with hard water, all while remaining environmentally friendly.

Suggested Use

Tossing a scoop into the washing machine is all it takes to soften water and get a better clean with each load.

Certain phosphates can safely eliminate problems associated with hard water and be environmentally friendly. They are only a problem with overuse. While septic is safe in general, if you use it daily, you may need to periodically replenish your septic system with an enzyme and germ replenishment product.
