To freshen a Tempur-Pedic pillow, the manufacturer recommends removing and washing the pillowcase and pillow cover. Roll the pillow in one direction, unroll it and roll it in the other direction to infuse the material with fresh air. To remove surface stains, dip a cotton towel in a mixture of mild soap and water, wring it out and gently dab it over the stain. Allow the material to dry fully.
Remove odors while freshening the pillow by evenly sprinkling baking soda over the surface. Allow the pillow to stand for approximately one day, and vacuum over the surface with a vacuum fitted with a brush attachment.
Allowing the pillow to breathe outside on a warm day is another effective method for freshening the material. Heavy-duty odors, such as those from pet urine, may require the use of a liquid enzymatic cleaner. Apply the cleaner according to manufacturer instructions, and allow the material to fully dry. Then, use the baking soda method to finish freshening the pillow.
Memory foam is a delicate material that breaks down when exposed to the agitation of a washing machine. Additionally, the dense foam traps moisture and requires long drying times. Otherwise, damp foam may breed mold and bacteria.
