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, providing nutrients to aid biodegradation. They become a problem only with overuse.


Charlie's Soap Booster and Hard Water Treatment uses a simple phosphate that:

  • Softens your wash water.
  • Allows Charlie's Soap for Laundry to work better in the wash.
  • Rinses completely leaving no residue on your clothes.
  • (at one tbsp. per wash) aids natural biodegradation in the environment.
  • Keeps your clothes and the environment clean. 


For Laundry:

Use at least 1/2 tbsp. of Charlie's Soap Booster as needed per wash.

Use 1 full tbsp. for tough stains or excessively hard water.

Wash according to care instructions.

Test garments that may bleed or fade.


To Pre-treat Stains:

Add 1 tsp. of Charlie's Soap Booster to Charlie's Soap Laundry Pre-Spray to tackle really bad stains.


For Household Cleaning:

Add 1/2 tbsp. of Charlie's Soap Booster per 32 oz. spray bottle of either Charlie's Soap Indoor/Outdoor or Charlie's Kitchen & Bath cleaners to make them even more powerful.
