I want to try it for smoke elimination which it says it will work for.

I haven't tried it, but it would probably work.

Interesting the other things it says it works on, though......

"pet urine saturated carpet, diaper pails, unwashable sports equipment, garbage...skunk..."

Hope you don't have any of that stuff in/on your car.....
