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.

excellent We live in an area with exceptionally hard water; this booster makes a big difference in our laundry! March 24, 2015
Works very well...!!! For my L/W (lights and whites), I use a scoop of this, plus a bit of Seventh Generation liquid non chlorine bleach (or Ecover non chlorine liquid bleach) and a scoop of Biokleen Chlorine Free Oxygen Bleach plus Powder and this works beautifully. Often times I leave the L/W soaking in the HE front loader washer for a few hours and will often turn on the machine and let it tumble for a few minutes before switching off. I have (MCS) so I can't tolerate many 'stinky' perfumy products including the awful toxic chlorine bleach. December 6, 2014
Booster Using along with Soap powder seems to be brightening white over a few washes. Using with warm wash cold rinse November 2, 2014
Won't wash without it If you don't have a water softener in your house, chances are you have some degree of hard water. This is a MUST, even if you do not use Charlies Soap Powder (which is a very good product). Hard water prevents soaps from cleaning well and makes the soap leave behind a dulling residue on your clothes, and in your machine! I had trouble with build up from national popular brand detergents. A few loads run with this booster and my machine sparkles like new. It not only prevents buildup, it will help wash away the old buildup you have. I used Charlies Soap for several years, then began making my own laundry detergent. The booster is the key to making ANY product clean well in hard water. I recently purchased a top-of-the-line dishwasher, that demands you use rinse agent in it. I do not. I add a teaspoon of this booster to the soap dispenser with my detergent and my dishes are spotless. The interior of my dishwasher sparkles also. This is a great product to off set the hard water we fight with in cleaning. March 19, 2014
Great! Tis booster works well, mild scent & I mostly use it when I hang my laundry outdoors, it helps the fabrics to stay soft since I do not use softeners. November 6, 2013
