Though some forms of bed pillows withstand machine washing, memory foam pillows do not nor should they be put in a drier. If the pillow is in need of a cleanup or freshening, spot-cleaning retains the foam in good shape. To maintain the pillow its cleanest and freshest, use a pillow cover or lining between the pillow and pillowcase, washing the cover as needed.
Memory Foam Pillow Care
Vacuum a memory foam pillow to remove dust, debris and hair which settles on the pillow as time passes. If the pillow has a removable protective liner or sleeve over it, remove the lining anytime you change the bedding to allow the pillow air out for an hour or 2; this helps release moisture or perspiration that the pillow absorbs out of routine use. Spot-clean soiled areas with a soft cloth dipped to mildly soapy cool water, wringing out nearly all of the water; then wipe again with a slightly moist cloth to remove any soap residue. Use a light touch after cleaning the pillow to prevent damaging the delicate polyurethane. Allow the pillow to dry thoroughly; a ceiling fan expedites the process.
