Place no more than two goose down pillows inside a commercial dryer, as smaller dryers are not large enough to dry the pillows thoroughly.
Put two tennis balls inside a clean white sock and toss it into the dryer with the pillows.
Set the dryer to medium heat and turn it on.
Stop the dryer and fluff the pillows every 20 to 30 minutes. Rub your hands over the pillows to locate lumps and break them apart to speed drying time. It may take up to three hours for the pillows to dry completely.
Remove the pillows from the dryer when they feel dry and the feathers no longer clump together.
