Do not use perfumed sprays or disinfectants to remove odor. They will only mask odor for a short while, and may interact chemically with smoke odor to create a new unpleasant smell.
Hang damaged items outside, preferably in sunlight, for 4-8 hours to air out. If weather does not permit, hang items in a location that was not damaged by fire. Soot remains in the air of the home or building where the fire happened, and will redeposit on clothing.
If airing out does not eliminate odor, contact professional fire restorers / dry cleaners and ask about “counteractants”. These chemicals, applied based on what material was burned in the fire, can help to break up smoke and odor particles in the fabric.
