Foam bed pillows can be washed at home to keep them smelling fresh and clean.
Use lukewarm water and a small amount of gentle detergent. Use enough water to cover the pillow and gently squeeze to move the detergent and water through the pillow. Rinse several times until the water runs clear. Gently squeeze the foam to remove water. Do not wring harshly.
Foam pillows should not be placed in a dryer because the high heat can ruin the foam and cause it to crumble. Allow the pillows to air dry on a flat surface. It is a good idea to launder the pillows on a sunny day so that you can put them outside in the sun for a final dry.
