Removes the laundry product residue and allergens from clothes and linens
I find that laundry boosters improve the efficiency of my (not very) high efficiency washer. Clothes and linens come out cleaner and softer; smell fresher without adding scent. Charlie's Soap Booster is the best product I have found for this purpose. it works exactly as advertised. At present I use 1 scoop per wash; I will probably reduce that to 1/2 scoop after all washables have been through one or 2 cycles with a full scoop and residues have been removed, including allergens from previous laundry products.

Sticky laundry no matter what you do? Charlie's Booster and Charlie's Soap WORKS!
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!

Must-have with hard water
This is a must if you have hard water! All the products are legit! It has no scent so it is clean to use on children’s clothes. Colors keep well!

Works as Advertised
I've been using their products for decades. Having lived with well water almost 40 years, I long ago learned that I needed help with hard water, and this does great. Their products are eco-friendly and cruelty-free, top priorities for me.

Good stuff!
We tried Charlie's Booster earlier this year, liked it because of it's ability to help with hard water. I went back to other large-label pods but they did not give us what Charlie's does. Definitely noticed that our washable items were soft and cleaner! We have terrible hard water at our home and so glad we found this! And we feel we are helping the environment at the same time. I gave 4 stars because we feel the packaging could be much better. I bought an air tight container to keep the powder in so we don't have to deal with the bag it comes in. There always seems to be powder on the outside and the zip-lock type of closure is not exactly user friendly.

Hard Water Helper!
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!

Most helpful water treatment!!!
This is a very helpful and versatile water treatment, because the laundromat that I utilize, their water supply smells like a sewer. This helps!!!

This has really lessened the white soap residue on dark clothes washed in hard water. It was recommended by a staff at local dry cleaner. So glad I found this product.

I move to an area with very hard water. Laundry soap on it's own would not get my clothes clean. The first load I tried with Charlie's Soap Laundry Booster was amazing. The clothes came out clean and had a nice fresh scent.

I bought this because I couldn’t get Calgon. It also works to soften your water. We use it in our RV holding tanks. It works also. Abe

Like because the soap gives a boost of whiteness to my white load.
