Following the Path the Smoke Took
Thermal fogging works on a simple principle: smoke penetrated the building as a heated, expanded aerosol, so the deodorizing agent has to travel the same way to reach the same places. A thermal fogger heats a solvent-based deodorizer into a dense fog of extremely fine particles that behave like the original smoke, migrating into wall cavities, under cabinets, behind trim, into upholstery and through porous materials that surface cleaning and ambient air treatment cannot reach.
