Wildfire smoke produces fine particles and odor molecules that settle into drywall, carpet padding, upholstery, HVAC ducts and wood framing. Any remaining ash or damaged contents need to be cleared before the fogging process starts.
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. Heavy wildfire odors sometimes call for more than one round of treatment.
