To prolong your pillows’ freshness, adopt good daily habits. Each morning, remove the pillowcases, open up the windows, and let sunlight bathe your pillows. This practice airs out your room and deters excess moisture and mold growth. And if your pillows look a bit drab? A steam cleaner can spruce them up. For a brighter touch, pre-soak them in a mix of lemon juice, white vinegar, or hydrogen peroxide before a machine wash.
