Fresh Air And Sunlight
One of the first things you can do to freshen up your bed pillows is to expose them to fresh air and sunlight. Take the cushions outside on a sunny day and let them air out for a few hours. Sunlight will help kill bacteria and mites that can grow on your pillows. Be sure to flip the pillows over to expose both sides to the sun’s rays.

Sodium Bicarbonate
Baking soda is an excellent natural remedy for removing unpleasant odors from pillows. Sprinkle a generous amount of baking soda on the pillows and leave it to act for at least 30 minutes, or even better overnight. The baking soda will absorb odors and make the pillows fresh. Afterwards, you can vacuum up the remaining baking soda with the help of a vacuum cleaner.

Lavender
Lavender is known for its delicious, relaxing scent. To refresh your bed pillows with this flower, you can make a simple solution. Take a cotton bag and fill it with dried lavender flowers. Place the bag between the pillows or inside the pillowcase. The delicate and calming fragrance of lavender will help create a relaxing and fragrant atmosphere in your bedroom.
