Auto Shocker Strong Car Odor Eliminator, Eco-Friendly Chlorine Dioxide Odor Bomb for Vehicle Interior Up to 250 Cubic Feet

We first used this in our house after having a house-sitter who smoked spent a weekend at our home. She smoked outside but the windows were open and the smell was so strong in our bedroom that we couldn't sleep. We tried multiple different things with very little improvement. This product completely got rid of the smoke smell. We have plants in our room and it didn't harm them at all. The smell of strong chlorine was intense while it was doing it's cleaning process so we just slept in the living room for one night. The chlorine smell lingered mildly for a day or two but it wasn't bad at all. It has been about 6 months since that first use and our room smells fresh, not a single bit of smoke smell. The second time we used it was when one of our children left the car door open overnight and a stray cat peed inside the car. Again, this product did a super great job completely eliminating the cat pee odor!

My wife and I found her dream car in terms of model, options, and color, which was kind of a unicorn since it was a combination of multiple rarer choices. However, we were then dismayed to discover that the interior smelled of cigarettes. We ended up buying the car anyway since it wasn't overpowering, but I immediately set off looking for a remedy. Most answers were that it would never come out even after expensive and/or time- and labor-intensive treatments since smoke adheres to practically everything more strongly than solvents can dissolve, and since it's a gas it can even get under fabric and porous leather -- but then somebody mentioned this. Further research on this specifically indicated that it had succeeded for people who had tried several other remedies with no success, so considering how simple and inexpensive it was, we gave it a shot.WOW! The smoke smell is now COMPLETELY gone, replaced briefly with a faint chlorine smell (like a swimming pool) from this since it's chlorine dioxide, but that goes away after no more than a few days and then there's no smell at all. This does NOT just layer a new smell on top of unpleasant odors. It actually reacts with the odor-causing particles in the car to neutralize them, and since this is a gas just like nicotine, it can go everywhere nicotine can to chase it down.We let this thing sit in the car for 22 hours in a garage and followed all of the included instructions, including jumping into the car to turn on the AC in recirculation mode (and then closing it up the again with the Auto Shocker still inside) for the final 15 minutes when the gas concentration is highest. Also, since the cigarette smell was also in the trunk area and we had fold-down seats, we wanted to treat that area too, but folding the seats all the way down would prevent their surfaces from getting treated, so prior to starting this treatment, we daisy-chained some zip ties together, ran them through the LATCH child safety seat loop behind the seats, and then around the metal headrest supports on the seats -- thereby suspending the rear seats partway down. Next, we covered the front, rear, and side glass with beach towels and a bed sheet since the product notes that UV makes it less effective (though this may have been overkill.) Finally, we changed the cabin air filter to an activated charcoal version just for a fresh start, although the car had a new standard air filter when we got it anyway. On most cars that requires no tools or expertise at all, and there's probably a YouTube video for whatever car you have. Just don't confuse the cabin air filter (aka microfilter) with the engine air filter!The results were better than we had dared to hope since we didn't think perfection was possible for something so inexpensive and simple, but that's exactly what we got. My wife is now over the moon since her dream car is now no longer tainted. HIGHLY recommended! (Note that after using this, just for completeness we also used Einszett 961108 to clean the AC evaporator core in case that reintroduced any smells into the cabin. That requires removing your AC blower fan, which is also pretty easy, but a mechanic could do this if needed. However, the overwhelming majority of the improvement came from this Auto Shocker, so you could also just use the Einszett 961108 if you find the smell coming back only when your AC/ventilation is running.)

I used it on a used car that had some dog odor. I shampooed all the seats, carpets and cleaned the windows and headliner. As a last step, I used this product, i let it sit for 24 hours, ran the AC in recycle for 15 mins as suggested and let it vent. The smell got slightly better but still there and I'm not a person sensitive to smells.The instruction manual directs you to their website for their return policy and this is what it says ... "There are really only two ways that they don't work: they are used incorrectly, or (rarely) there is a packaging defect". So there wasn't any problems with the package now they are going to say that I use it incorrectly even though I followed every single step on the instructions?(The TIPS are listed after all the 9 steps, its funny that step #9 says to place lid back on the Auto Shocker but then it says on step 10 to allow vehicle to ventilate before entering ...how can I put the lid back and open all doors for ventilation if I'm not supposed to enter the vehicle for at least 20 mins ... So even if I were to try to get the money back, they want me to send the foil package that was properly disposed per their instructions ... and spend a bunch of time on shipping, an invoice should suffice but that's their way around it. So read reviews outside Amazon before buying this and check their BBB rating. Don't waste your $$$

If you've been in a newly opened pool, the smell should be tolerable once you run the fan and open the doors as directed. It was easy to use but as I discovered this time, it is important to dump the chlorine packet directly from the foil packet into the bucket. I forgot this time and tried to pull it out of the foil packet. It may as well been made cotton candy. It tore open and when I poured the water in, a greenish yellow foam grew and ran over the sides of the bucket so I couldn't use it. I will also recommend cleaning your interior glass AFTER this treatment. I had a slight film develop but that may have been from getting my windows tinted. Or a combination of both. I used one in my car after smoking in it for 7 years. It removed all cigarette odors in my car. The chlorine smell fades quickly and leaves a neutral smell in a few days. No smoke smell. DEFINITELY read and follow the directions exactly and you shouldn't have a problem. Absolutely run your fan before opening the doors to air it out. I let my fan run for 30 minutes because I let the Biocide work in my car for 24 hours. Great product. Easy to use.

This product is great. I had a lingering smell from some dog accidents in my car that I could just not get rid of, even with an expensive detail. I used this the other night and the next day no smell! Definitely going to keep some stocked for the future.
