Feather and down pillows can be cleaned in your machine, but make sure there are no slits or tears in the covers and that the ticking is secure. For balance, load two pillows at a time and use only a small amount of detergent. Set the machine on the delicate cycle and give the pillows a second rinse. For drying, place them in the dryer with several clean tennis shoes, which will aid in the fluffing process. It’s also a good idea to take them out periodically and fluff by hand; use your fingers to break up any clumps. Pillows will take longer to dry than a normal load of clothes. If they have a musty smell, set them in the sun for a couple of hours.
