Fabric Rinse is designed as a laundry detergent booster to help remove stubborn odors and residues deep within fabrics that detergent leaves behind*. Rinse fights odors in just one wash and leaves your clothes with a fresh cotton scent. This laundry rinse is different than a laundry sanitizer or a fabric softener. Rinse is formulated to break down and rinse out odors at the source, vs cover it up. Rinse works significantly better than vinegar** and doesnt require soaking. Gentle on skin and safe on all washable fabrics, Rinse is a must-add to your laundry routine.  Smelly activewear, musty towels, stinky pet bedding, even forgotten laundry in your washing machine overnight - Rinse is the product for you. Just add detergent then pour Rinse into the fabric softener drawer or directly into the rinse cycle to tackle odors. Includes one 16 fl oz bottle of Rinse Out Odor Laundry Rinse in the Cool Cotton scent. (*removes more odor in one wash than the leading value detergent in 3 washes **based on odor and stain removal vs leading national vinegar brand.)
