Make laundry smell delightfully fresh for months with Downy Unstopables In-Wash Scent Booster Beads. These special scent enhancers make clothing, towels, sheets, curtains, and more smell fantastic for up to 12 weeks after washing. Downy Booster Beads are small laundry scent beads that work inside your washing machine, gradually releasing fragrance during the wash cycle. They're safe to use with all washing machines, including HE models. Before adding clothes, simply shake as many Downy Unstopables as desired into the cap, and then toss them into the washer drum. Use scent booster beads along with your laundry detergent and fabric softener for long-lasting freshness.
