After the fire has been extinguished, you are left to deal with the aftermath, such as cleanup. The smoke that naturally occurs with fires will attach itself to surfaces and fibers. This odor can last for weeks and even months after the initial incident. A mattress will absorb the odor and become trapped in the fibers. The size of the mattress makes cleaning difficult. Unlike clothing, you cannot merely launder the mattress in a washing machine. Instead, you must remove the fire smell from the mattress by hand.
Remove the bedding from the mattress. Launder the bedding as you normally would with the appropriate amount of laundry detergent and 2 cups of white vinegar.
Fill a spray bottle with white vinegar. Saturate the mattress liberally with the vinegar. Allow the vinegar to air dry on the mattress. Vinegar is an all-natural deodorizer that will kill fungus and eliminate odor.
Sprinkle baking soda liberally onto the mattress after the vinegar has dried. Scrub the baking soda into the mattress with a scrub brush. Allow the baking soda to sit on the mattress for 24 hours.
Secure the upholstery attachment to your vacuum's hose. Remove the baking soda from the mattress with the upholstery brush.
Repeat the process as needed until you have removed the fire odor.
