It's not like it's impossible to remove odors with chemical means. A very concrete example: The way lingering smoke damage is treated after scrubbing off the soot is with ozone. The smoke smell is from volatile partially oxidized hydrocarbons, and ozone just loves getting rid of an oxygen molecule and becoming O^2.
It's at least conceivable that there would be less noxious options available than ozone. An old trick is to use vinegar, seems to work.
