The Kirkland Signature Ultra Fresh In-Wash Scent Booster delivers a light, clean Spring Fresh fragrance that clings to fabrics throughout the wash cycle and long after laundry is done. Available in a large 45.9-ounce container, this Costco-exclusive product provides excellent value compared to name-brand alternatives.

Simply pour the desired amount of beads directly into the washing machine drum before adding clothes, or place them on top of your laundry. The beads dissolve during the wash, infusing fabrics with a long-lasting spring fresh scent. Compatible with both standard and high-efficiency (HE) washing machines, the formula is safe for all colors, fabrics, and load types, including athletic and activewear. The 3.3-pound container delivers many loads per purchase, making it a cost-effective choice for households with frequent laundry needs.
