So, bro, I think the answer here is obvious, to get rid of the smell of cigarettes in the car, you need to stop smoking in it. The smell will certainly be present in the cabin, but after some time it will completely disappear. If the smell does not go away for a long time or you want to speed up the process of weathering this nasty smell, then you can use the smoke odor eliminator car and the process will be much faster. I had a terrible mildew smell in my car that I couldn't clean up. I waited for a long time and left the car open in the sun, but nothing helped. I bought this spray and everything went away after a while. I advise you to try, I think it will help you.
