In this historical case, a customer prepared a smoker's car before sale and included odour work in the interior treatment.

Smoke residue settles on glass, plastics, headlining, textiles and ventilation surfaces. Those sources must be cleaned; distributing a vapour alone does not remove them.

A compatible neutralisation process may follow after cleaning, with controlled exposure and thorough ventilation. It should not be described as eliminating every bacterium, fungus or concealed particle.

Odour can return where residue remains or smoking continues. AVP therefore explains likely improvement and limits after inspecting the vehicle.
