This isn't exactly e-cig related, but since I've stopped smoking, I'm starting to notice just how badly my car smells. As easy as it would be to just get a new car, that isn't in the budget, so what worked for you?
First wipe down everything you can reach to remove any cigarette residue. Use glass cleaner on the windows to remove the cigarette haze.
Vacuum and Febreeze all cloth surfaces. Place bowls of vinegar around the car and leave in the car overnight. That will get the smell out of the seat padding and head liner.
The hard part for me was getting the smell out of the AC system. I changed the filter but that didn't help much. I tried running the AC with vinegar, a cloud of Febreeze, dryer sheets, Ozium and such but at best they only masked the smell until I let the car sit for a few hours. As soon as I hit the AC again, it was like someone had just lit up. My local auto parts store has a fogger type odor neutralizer (I'm sure they're easily found online as well). I put that in the car with the AC running for 20 minutes, then quickly jumped in an switched it over to the heater for another 20 minutes. It had a heavy scent that took several days to disperse and I couldn't breathe in the car unless I kept the windows down for about 3 days. But there's absolutely no hint of cigarette smell left in the car now.
How do you change the filter for the AC??? I have a Honda Odyssey...
