Cigarette Odors in Car

This is an old used car dealers trick. Take a 2 lb can of any type ground coffee and cut up two onions in big chunks, mix this with water in a large metal boiling pot, like the kind you cook pasta or corn on the cob. Put it in the back seat and roll up the windows and let it bake in the sun for 1 day. Throw the mixture away and roll down the windows for an hour or so and now you have a nice smelling car. I didn't believe it until we got a car that was so bad, the white on the interior was yellow, of course you have to clean the interior first.
