Ozone generator

Get a carpet cleaner like Bissell that you can pump and suck cleaner out of and go over every inch of carpet, seat and headliner. The smell is soaked into the materials and just using a rag to spot clean it won’t be enough. Then scent bombs

You could try sprinkling the carpet with baking soda and brushing it in, and then vacuuming it out. it also sounds like you didn’t change the cabin air filter which should help as well.

Also if it’s a nice day out or you have a garage just leave all the windows down for as long as possible. If it’s in the garage maybe run a fan to help.

Ozone machine for a few days with the HVAC blower on.

I’m surprised Ozium spray didn’t handle it. I can’t stand the smoke smell either. People who are non-smokers don’t realize. Glad I quit 25 years ago. Have two ex GFs and an exwife who smoked.

Bought an '86 CRX quite a few years ago for $100. The carpet and seats were full of cigarette holes. Only way I was able to get rid of the smell in that car was to yank the carpet out and reupholster the seats. Thankfully I have the skills and tools for that but the smell in that thing wasn’t coming out otherwise.

When you ozoned it, did you leave the ac running on recirculate? I had an issue with my car and did this and it worked fine

Misread this as “tips for removing doors” and was about to recommend an impact driver

The biggest shame is: if the person was more responsible, there would be zero (or little) smell. I’ve smoked both cigarettes and cigars in many new (leased) and used cars. Open windows before you smoke. When you finish smoking, drive around with windows open until your destination. Leave windows cracked overnight. Never had somebody notice it was “a smoker’s car”.

Buy a few of those charcoal odor absorber and leave them in the car

Ozone had the biggest impact for me, but to be honest, you’ll never get all of the smell out.

Certainly way, WAY, more managable…but never completely gone

I bought a smokers car that made me nauseous driving it. It’s like the owner smoked with all the windows up. I did tons of cleaning - like vacuuming with a Dyson stick with the little rotating brush, spraying and wiping everything. I’ve done the bombs like ozium and meguiars, and bought an ozone machine off Amazon. The smell is so much better and have even gotten comments that it smells like a new car which to me is still slightly smokey. I want to use my upholstery cleaner on the carpet but I’ve been too lazy since the smell is mostly gone and doesn’t bother me anymore. Repeated two hour ozone treatments I think work the best out of any other methods I tried. People suck oziums ass but I think that shit sucks and only masks the smell and it smells terrible.

Don’t buy smoked in cars. The smell never goes away.

smoke some cigarettes in it that usually fixes the issue

Pooph oder remover. Seriously

Ozone treatment… you mean you used one of those electric O3 generators? I’ve had to do two 30 minute sessions with the AC on full, recycle and the AC air filter removed just to finish off smoking odors. Does the headliner smell?
