Quick Answer
Most memory foam pillows should not be machine washed or soaked. Remove and wash the cover according to its care label, and spot-clean the foam only if the manufacturer allows it.
How to Wash Memory Foam Pillow
Check the pillow's care label and manufacturer instructions first, since construction and materials vary. If the cover is removable, wash it separately as directed. For the foam, spot-clean small stains with a cloth lightly dampened with cool water and a little mild detergent, if permitted. Blot gently rather than rubbing, and avoid soaking or submerging the foam.
How to Dry Memory Foam Pillow
Blot away moisture with a clean towel, then air-dry the pillow completely in a well-ventilated area before putting the cover back on. Keep it away from direct heat. Do not tumble-dry the foam unless the manufacturer specifically permits it.
What to Avoid
Do not machine-wash, wring, twist, or soak the foam unless the care instructions explicitly allow it. Avoid bleach, harsh cleaners, and putting damp foam back into a pillowcase.
Important Warnings
Waterlogged memory foam can be difficult to dry and may be damaged. Do not wash pillows with built-in electronics or other components unless the manufacturer provides specific instructions.
