Proper pillow maintenance is key to preserving its shape, hygiene, and comfort. Regularly washing your pillow cover and using a protective case can prevent dirt, sweat, and allergens from accumulating. Memory foam pillows should be spot-cleaned with a damp cloth, while most synthetic and down pillows can be machine-washed according to their care instructions. Fluffing your pillow daily helps maintain its loft and prevent it from becoming flat or lumpy. Additionally, airing out your pillow in direct sunlight every few months can help kill bacteria and remove odors. Following these maintenance tips can extend your pillow's lifespan and ensure consistent comfort.
