Quickest way to lose the bad odour from "memory foam" pillows?
What is the fastest way to get rid of that awful smell that comes from new memory foam pillows?
I’ve had my pillow for about 2 weeks now and it still smells enough to not be usable. I have taken the plastic of and left it to air out.

wash it in a cold water wash made for sweaters and let it dry out, repeat as needed
Throw it away.
Would spraying it with a perfume or fabreze or lysol work?
Leave it to air air for a few days, it may take 2 days, or a week, it depends on how badly it smells, or how ventalated the place you took to air it is.
