Can Oust remove cigarette smoke?

Yes it will if there isn't much of it. I use everything to get rid of cigarette smoke and film. vinegar left in a small dish overnight will do a good job too. I also use Frebreeze. Mostly the cigarette smoke clings to your walls and furniture even if you use Oust to help remove the smell. we both smoke and I am always washing off walls with ammonia and baking soda, rinsing with white vinegar and water. It always makes it look new again. The film is awful dirty and filthy yellowish/brown. So it is quite a job to keep doing it. It would be better to quit smoking but quite difficult because my other half won't quit. If you are lucky and just a little bit of smoking was done the Oust will do a good Job.
