Short backstory: My cousin (closest I have to a brother) has gotten a job out in california and is moving there in February, and along with the new job he's trying to make some other changes in his life, one of which is quitting smoking. We have been on him for a while to stop and he is finally giving it a try, been smoke-free for a week now after 10 years. Anyways, he left his car with me while he goes out for training, because he can't afford some of the service on it right now to get it out there with him, and I told him I would fix it for free. As a bonus gift, I'd like to try and get all the cigarette smell out because I know it would make a huge difference to him since he's been working so hard to get cigarettes out of his life. Does anyone know any home remedies or good commercial products for getting rid of the smell? Anyone know what the dealerships use? I know I'm going to have to clean close to every square inch of the interior as well as change out any cabin air filters, but any help would be greatly appreciated. Alternatively, if you know any good places that can get the job done for a reasonable price I may have to resort to that option if doing it myself doesn't work out.
