Kao Humming “Deodorizing Experience” Fabric Softener in Refreshing Green Scent (refill, approx. 950 ml) is a Japanese laundry softener designed for powerful odor control and softness. It tackles musty, indoor drying, sweat and sock odors with superior antibacterial performance—the top among Humming variants—and employs Attack’s advanced deodorizing technology to block odor return even when clothes get wet again. It also inhibits mold in the wash drum, prevents static buildup and pollen clinging, and leaves laundry softly scented with fresh citrus-green and uplifting white floral notes. Ideal for everyday use when drying indoors or for fabrics prone to strong odors.
