How can I remove smoke odor after a fire?
As commented, this is usually part of the mitigation company's deal, as the tools are a bit specialized (serious ozone generators, for one thing) and they may have access to ones a bit more serious than any you may be able to find to rent, as the rental company may not be comfortable with the hazard level of putting those in consumer hands.
Other methods they might use include using the upholstered furniture mode of a typical &quot;rug cleaner&quot; (spray wet solution and vacuum it out, generally with a smaller nozzle for furniture than for a floor.)
