Remove any Lingering Scent
coffee groundsIt’s possible that all your cleaning efforts have still left behind a slight smell. If that’s the case, you should place an air freshener near the vents and allow the vents to operate on high for about half an hour. Just let the air circulate, with the windows open to cleanse your car of the smell. This not only removes the smell of smoke that may still be left behind, but it also gets rid of the smell of the cleaning chemicals you have used, making your car smell fresh again.
If you want to replace or overpower the scent of smoke, you can use coffee grounds. After you have completed your cleaning, you can place a pan of coffee grounds inside your car, with all the windows closed. Leave if for a few hours, and your car should be permeated with the new smell quickly. Of course, if you don’t like the smell of ground coffee, then this won’t really be an option, but there are other strong-smelling scents you can use to replace the smell of smoke.
