Best air freshener/air deodorizer.

[Snake Plissken]

X-O Odor Neutralizer to start with. Use a 1:8 oz mixture, which is roughly double the recommended dilution. Mist over all the fabric parts and carpeting and wipe down any of the lesser porous surfaces.

After that dries, sprinkle some baking soda into the carpeting and on the seats, and vacuum after appx. a half-hour.

If you have access to an ozone machine, run it in the closed car for a day.
