Burned contents and structural charring produce smoke particles and odor molecules that settle into drywall, carpet padding, upholstery, HVAC ducts and wood framing. Initial soot cleanup and removal of badly damaged items should occur before fogging begins.
A heated deodorizing solution is released as a fine fog that travels into the same porous materials the odor reached, then binds with and neutralizes odor molecules. The space must be empty of people and pets during treatment and ventilated afterward. Severe cases in Elk River, ID sometimes require follow-up applications.
