Whether you're dealing with bad smells in memory foam or foul odor from couch cushions, getting a bad smell out of foam is much harder than practicing a few preventative techniques. But fortunately, when changing sheets or cushions and keeping them clean has failed to keep smells out, or when your expensive foam mattress topper has a close encounter with bodily functions or ends up smelling like cigarette smoke, there are a few things you can try.
Step 1
Allow your foam mattress, mattress topper, pillow or cushions to air out in a well-ventilated area for at least 24 hours. This will help to dissipate any remaining chemical odors.

Step 2
Treat any remaining odor by sprinkling baking soda liberally over the foam and letting it sit overnight in a well-ventilated area.
Step 3
Vacuum the foam thoroughly with a hand vac or the soft brush attachment on a vacuum cleaner.
Step 4
Turn the foam over and sprinkle the other side with baking soda, too. Let sit overnight, in a well-ventilated area, once more.
Step 5
Vacuum the foam again. You can repeat the sprinkling and vacuum process with baking soda if necessary. You can also spritz the foam with either vinegar or a citrus-based cleanser, let dry, and then vacuum thoroughly.
