When you add Ultra Downy it depends a great deal on your washer type. These days, fabric softener is easier to use than ever: Regular machines — With regular machines, add Ultra Downy to your washer drum during the rinse cycle. Or for added convenience, try the Downy Ball®, our easy-to-use dispenser. HE machines — With HE machines, you have a built-in, automatic solution. Simply add Ultra Downy to the fabric-softener tray (often right next to the detergent tray) before each load.
