## Overview

Charlie's Soap Laundry Booster is a powerful, non-toxic hard water treatment that softens water by removing minerals like calcium, enhancing detergent performance without leaving residues. Its biodegradable, phosphate-free formula is safe for sensitive skin, septic systems, and the environment, helping you achieve fresher, softer laundry faster while reducing water and energy use.

## 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.

Review: 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.
Review: 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!
