My only problem now is I'm paranoid about lighting another cigarette in the car because I don't want to mess it up again. Guess that's a good problem to have.
Used it before a long drive with my family because nobody else in the family smokes and I didn't want them sitting in the old cigarette smell for six hours. Nobody complained once. That's basically a miracle in my family 😂
I don't write many reviews but I would've appreciated knowing this actually worked before I bought it. So here you go: heavy smoker, cloth interior, years of smoking in the car. Very noticeable improvement.
After a camping weekend my SUV smelled like damp tent, campfire, dirty shoes and snacks all rolled into one. This was exactly what it needed after I unloaded everything.
Love love love it.
I've smoked in several vehicles over the years and always assumed once a car had that smell, it had it forever. Apparently I was wrong.
Three-hour road trip with two muddy dogs in the back. Came home, cleaned the SUV and treated the odor. Worked like a charm.
Honestly just happy I don't have to apologize before somebody gets in my car anymore.
I stopped smoking cigarettes but kept finding old reminders everywhere in the car. Lighter in the console, empty pack under the seat, ash around the cupholder. Deep cleaned all of it and then used this. Now getting behind the wheel actually feels fresh instead of like stepping back into the habit.
Very impressed with the results in my Jeep.
Gym clothes sat behind my seat for several days during a heat wave. I take full responsibility for this disaster. This helped tremendously.
I smoked with the sunroof open thinking I had somehow outsmarted cigarette odor. I had not 😂 Smell Slayer fixed what my brilliant strategy didn't.
My dog gets carsick sometimes. Enough said. This has been VERY useful.
I travel for sales and basically live out of my car Monday through Friday. Coffee, lunch, paperwork and, until recently, cigarettes all happened in there. I cleaned everything before using this and afterward the cabin felt genuinely reset. Really nice not sitting in stale smoke for hours every day.
Not gonna lie, pretty damn good.
I quit smoking inside the car about a month before buying this. Even after a month, you could still smell cigarettes every time the sun warmed up the seats. Used Smell Slayer and finally stopped getting that blast of old smoke.
My car had this stale damp smell after sitting unused for a while. Cleaned it up and used this. Made a noticeable difference.
My biggest concern was that it would replace cigarette odor with some super strong chemical or floral scent. Nope. The interior just smelled neutral afterward. Exactly right.
Dog smell gone. Hair unfortunately still everywhere 😂
Used this in my old work van. I smoked inside it daily and it had gotten to the point where even I thought it smelled bad. That's saying something. Much better now.
No smoke smell when I opened the door this morning. That's a win.
Cigarettes were basically part of my driving routine: start car, coffee in cupholder, light cigarette. I've broken that routine now and wanted the car itself to stop reminding me of it. This helped more than I expected.
Picked up seafood and apparently some liquid leaked out of the bag onto the trunk mat. That was a fun discovery the next day. Cleaned the mat but the smell hung around. Not anymore.
LOVE IT. My truck smells so much better.
I'm a pretty skeptical person when something claims to remove smells instead of covering them. But the difference here was obvious.
This worked really well after transporting my sister's giant hairy dog for a week. 😂
My Accord has over 200k miles and I've smoked in it for a good chunk of those. I'm not expecting miracles from anything at this point, but Smell Slayer did a damn good job.
I genuinely didn't know my car smelled THAT strongly until a coworker rode with me and mentioned it. Kind of embarrassing. Treated the interior that weekend. Wish I'd done it sooner.
smoked in my car for years. Used this. Huge improvement.
Left damp beach chairs and towels in the cargo area overnight. Everything smelled funky afterward even once it dried. This cleaned up the lingering odor nicely.
My daughter has been nagging me forever about smoking in my car. I finally stopped and told her I'd get the smell out too. She got in yesterday, looked around and said "Okay, I'm impressed." 😂 I'll take it.
