It’s spring cleaning time in my house and we usually work from the bedrooms on out. Pillows often get overlooked, but they need to be cleaned too. If you’ve got a feather, down or polyester pillow, you can put it in the washing machine. This is one exception I make when it comes to water temperature. I do use warm or hot water on pillows. Dry the pillows on low heat and use at least two dryer balls, but I don’t recommend tennis balls. And make sure the pillows are completely dry. If you have a memory foam pillow, sprinkle it with baking soda and leave it in the sunshine all day.
