Description

Some wander this Earth seeking wisdom. A lot of folks Charlie talks with are looking to beat hard water. Our Booster is a hard-water treatment made from a non-toxic biodegradable phosphate that brings out the best of Charlie’s Soap without leaving any residues on your clothes. It controls minerals in your wash water with just 1/2 tablespoon per load. Your septic system and washing machine will be safe, too, because Booster is completely soluble.

    • Wonderful laundry detergent to use!
Product Packaging: Retail
I would suggest trying other detergents and then try Charlie's laundry soap WITH the booster added to the washer's drum ... then, you can make an accurate assessment of which brand you really like and believe in. At least, this is how I evaluated it for myself. I have hard water and though the Booster is expensive, I have used it 2x and am seeing/feeling a difference in my clothes. Now, I have not found any detergent to remove sweat stains on a collar (miraculously) in one wash, but, Charlie's detergent seems to be able to do everything else as far as getting clothes so nice and clean. And, his Booster product assists the detergent in improving with each wash. I do not regret getting these products. If you do NOT have hard water, you'll never need the Booster, but, if you want really clean clothes without a scent, and also good for the environment, you might want to consider trying this particular brand! Thank you. ... show more

So far so good. I've only used it a few times, but laundry seems much softer and cleaner especially whites!

    • Hard Water Helper!
Product Packaging: Retail
Where we live we have very hard water. This soap really helps soften the water to keep clothes lasting longer. There is zero scent. Zero residue. Great for an added boost to your liquid detergent. Dissolves quickly, no clumping and a little goes a long way!

    • Seems to help make my clothes cleaner
Product Packaging: Retail
One of my regular subscriptions. I feel like this helps my clothes get cleaner, especially since I have hard water in my house, but honestly haven’t really been able to prove one way or another. But it makes me feel better to add a scoop of this to every load of laundry since it’s easy enough to do. This laundry booster doesn’t have any fragrance and adding it doesn’t irritate my son’s eczema-prone skin. So I’ll continue to use it unless I feel like it really doesn’t work. ... show more

    • Sticky laundry no matter what you do? Charlie's Booster and Charlie's Soap WORKS!
Product Packaging: Retail
I have been struggling with sticky towels and laundry no matter what I do. I have horrible hard water. Tried more soap/detergent, less soap/detergent, did the tub clean over and over, did wash with 3 extra rinses... Never used fabric softener. Tried vinegar on and on and on... UNTIL Charlie's Soap used WITH Charlie's Booster... I have an HE front loader... Followed directions for first use... (might take 2-3 washes initially to get residue out of laundry) IMPORTANT. Then did towels - washed twice per first use instructions... Amazing. And I only did the wash cycle without the extra rinses. What captured my interest about Charlie's Soap is the selling point of how well it rinses... coupled with the Charlie's Booster. It only took 2 washes with only 1 rinse (compared to the 3 extra rinses I used to use). So instead of each load taking 2 or more hours... it's down to 35 minutes. So saving electricity as well as time and water. Laundry is soft. Stickiness GONE! ... show more

    • tired of smelly clothes
I love this product so much, I had to write my first ever product review on this product. We have very very hard water in our home. It's so hard that we LITERALLY have to use a pumice stone to clean the hard water stains from off of our toilets and shower, and I do mean literally; any hard water stain cleaner such as CLR just doesn't do anything at all. Anyways, for several years we have had to put up with smelly and dingy clothes. Sometimes our clothes would smell so bad after being washed, that we would have to throw it straight back in the dirty laundry pile. Our clothes would always have this "faint and distant" smell of sour milk and urine. Although on hot and humid days this smell would not be so distant anymore, but in your face (nose) stinky. It was embarrassing to stand too close to people knowing how bad I smelled. In fact for years ( about a decade) I have been taking my clothes to get dry cleaned, instead of laundered at home, because as a business professional, I obviously can't walk around smelling like sour milk and urine. However, my wife still laundered my under clothes, tee shirts, briefs, and socks, because it would be too cost prohibitive to get those dry cleaned as well. Nonetheless, that smell would still manifest itself in what seemed the worst possible moments. The straw that broke the camels back was when I had my first meeting with a high level administrator in my new job and I was trying to make a good first impression, and there I was smelling like sour milk and urine (it was an especially hot and humid day). I had had enough! I went online and did some research and came across this product. So based on the reviews I bought it. And I did my own laundry using this product. And for the first time in several years my clothes smelled clean. I had forgotten how clean clothes were supposed to smell like, and it smelled wonderful. I would pick up every single piece of under clothes and press it tightly against my nose and take deep breathes through each garment trying to pick up the faintest smell of sour milk and urine, but it had COMPLETELY VANISHED!!!!!! Our clothes now smell fresh and clean. I love it! My kids love it! And my wife loves it! I buy this stuff two or three cans at a time. We will not do any laundry without it. I wish they sold it in bigger containers. Don't hesitate. Buy it. IT WORKS GREAT!!!!!!!! ... show more
