o keep your pillows smelling fresh, sprinkle a little baking soda on them and let it sit for 15-30 minutes before vacuuming it off. This helps absorb odors and moisture. For an extra fresh scent, lightly mist your pillows with a fabric refresher or a mixture of water and a few drops of essential oil (like lavender or eucalyptus). Also, wash pillowcases weekly and pillows every 3-6 months to maintain cleanliness and freshness.
