you can buy something of eBay or some stores called cinnamon extract spray. you spray it around your house and it makes it smell like cinnamon. i use it to get the smell out of my room cus i am still in my parents house and it dose wonders
Don't smoke to begin with! It's a filthy habit, and makes the house stink.Odor Control Plus worked well for me...good for like furniture, rugs, curtains, etc. I got it at www.cleanleafproducts.com.
I'd rent a carpet cleaner and use the upholstery attachment to clean the seats if they are fabric. Add a bottle of Odor Remover to the cleaning solution. They sell it where they rent carpet cleaners....
