How do you remove odors from foam cushions?

To remove odors from foam cushions, start by sprinkling baking soda evenly over the surface and letting it sit for several hours or overnight to absorb odors. Afterwards, vacuum the baking soda thoroughly. For deeper cleaning, you can lightly spray a mixture of water and mild detergent on the cushions, wipe with a cloth, and ensure they dry completely in a well-ventilated area. If the odor persists, consider using a fabric-safe odor eliminator or placing the cushions outside in fresh air for a few hours.
