Charlie's Soap Laundry Booster for Hard Water

Charlie’s Soap Biodegradable Booster & Hard Water Treatment boosts your laundry detergent’s cleaning ability to give your laundry a deeper clean by controlling hard water and removing the build-up it leaves behind on your clothes and in your washing machine.

Hard water minerals like calcium and magnesium leave a residue on your clothes, making fabrics look dull and feel rough to the touch. It can also cause “scale” (also known as “limescale”) or mineral buildup in pipes and plumbing fixtures, reducing the effectiveness of both your laundry detergent and your washer.

Charlie’s Soap Booster & Hard Water Treatment is a biodegradable phosphate that eliminates problems associated with hard water and aids with natural biodegradation of compounds in nature. By controlling hard water conditions, our Booster lets you get the bright, clean, softer, odor-free laundry you love, without the damaging residue.

Charlie’s Soap Natural Booster & Hard Water Treatment Features

• Fragrance-free
• Works in both traditional top-loading washers and HE machines
• Powerfully removes the effects of hard water, but is still gentle on sensitive skin
• Safe for all septic systems
• Effective in hot water and cold water cycles

Charlie’s Soap Natural Booster & Hard Water Treatment Benefits

• Enjoy clothes longer. The effects of hard water residues can weaken your fabrics’ fibers, shortening their lifespan. Our Booster & Hard Water Treatment cleans your clothes without the mineral buildup, meaning you can enjoy them longer. 
• Environmentally friendly. Our biodegradable booster is made from an environmentally safe phosphate that softens water and leaves no hard water scale.
• Sensitive skin friendly. Rinses completely from fabric, leaving behind no additives or residue on your clothes that can irritate sensitive skin. One of our most popular uses is for cloth diapers.
• Save Money. Skip the expensive water softening system, but still gain softer clothes with an affordable, all-natural laundry soap. Both your washer and your skin will thank you.  Our 2.64 lbs bag can treat up to 160 loads of laundry.  Compare that to other water softeners that only treat a few loads.

How to Use Charlie’s Soap Natural Booster & Hard Water Treatment

If you have hard water issues, use at least ½ tbsp of Charlie’s Soap Natural Booster & Hard Water Treatment per wash, pouring directly into the drum. Use 1 full tbsp for tough stains or excessively hard water. Works most effectively when combined with the cleaning power of our Natural Liquid Laundry Detergent or our Natural Powder Detergent. We recommend using hot water during your cycle, so that the water temperatureallows the products to fully dissolve and work their magic.

It can take several wash cycles to remove the initial hard water build up in your clothes, but after just a few laundry days, you’ll see your laundry detergent work harder with noticeably brighter, softer, and exceptionally clean clothes, without the need for bleach, brighteners, or fabric softeners.

This hard water treatment product is eco-friendly and safe to use in all washing machines, including traditional, top loaders and high-efficiencyfront loading washing machines.
