Laundry detergent not doing the job? Give your laundry detergent a boost and remove difficult, set-in odors from pet bedding, sports apparel, linens and more! Add 2 to 4 capfuls during the wash or rinse cycle—depending on the strength of the odors. When your laundry is done...so are the odors. (Use with laundry detergent to remove odors.) Does your front-load washer stink? Fresh Wave can tackle that too! Wet a soft cloth with Laundry Booster. Wipe the rubber gasket, the door, and any other visible seals. Wipe dry. Smile. No more smelly washer.
