GENTLE: Our formula is consciously formulated with 100% bio and mineral-based ingredients. We left out all the harsh chemicals, fillers, toxins, and pollutants commonly found in other boosters to create a hyperefficient, nontoxic, biodegradable formula. We only use the good stuff so your body and the environment are left as clean as your detergent. EFFECTIVE: Our advanced 4-in-1 formula is the first laundry product in the US to feature a groundbreaking bioenzyme that breaks down tough-to-remove “biological” stains and odors caused by sweat, body grime, and blood. (Think ring around the collar, yellow pit stains, weird grey or yellow stains on your favorite white sheets, and other stains.) ENVIRONMENTALLY FRIENDLY: At Dirty Labs – Less is More. By creating hyper-concentrated formulas, we greatly reduce our package sizes (and thus, our carbon footprint). Our packaging is made of recyclable cardboard. Our scoop is made from responsibly sourced schima superba wood. Our materials are responsibly sourced and extracted directly from nature. We examine every aspect of our product life cycles in order to achieve the safest, most sustainable solutions. DIRECTIONS: Follow your washer and garment care label instructions.
