ODOR-CLO2 Chlorine Dioxide Odor Removal - Air Freshener & Deodorizer

Be extremely cautious when using this! I wore a chemical respirator and goggles when setting it up and the smell was still overwhelming and potentially dangerous. DO NOT UNDER ANY CIRCUMSTANCES BREATHE IN THE GAS! It starts reacting instantly and no readily available equipment will protect you from it. Hold your breath, dump it in water and RUN don't look back or delay for anything. I used the entire bag for a 1200sqft apartment and it worked very well for removing the old pet/mildew smell. I set it up in a 5 gallon bucket with an air stone by the intake to the HVAC system and let it circulate for 24 hours. After 24 hours the smell is still very strong so I'd recommend having a chemical respirator for going in to open windows, at that point it was weak enough the respirator could handle it. But strong enough you don't want to breathe it. There was a faint residual chlorine smell for about a week that was very pleasant in my opinion but is now completely gone. I did the treatment about 5 months ago and it's permanently removed about 95% of the smell. It's good enough for me but I'm pretty sure if I did another treatment it would completely take care of it.

Purchased a used car that had a smoke smell. I had the car fully detailed and spent a small fortune on ozone and was still left with a smell that would reappear when the car sat in the sun. The ozone did seem to clear the vent system out, but I needed to find something that would get the rest of the smell out of the upholstery. Ozone made me nervous with the possible break down of rubber, electronics and leather, so I did only 2 hours of ozone (though detailer said I needed to do 3-4) and didn't want to do it again for fear of running the interior. After much research, I found companies offering a chlorine dioxide service, but then came across this product. The reviews, ease, and cost sold me and without fear of harm to the interior. Like ozone, I wanted to do the less approach and see the outcome as I could retreat without worry to the electronics and rubbers. The instructions state to park in shade, but that was not possible so I put blankets all over the car blocking out 100% of the sun. I future followed the instructions and used 2oz of warm water to 20 tablets. I put the water in a plastic cup that was 5" tall and put that cup in a plastic shoe box container in case of over foaming or spillage. I laid the back seats down to be able to treat the trunk area as well. Since the car was small, I placed the water container in the backseat on the floorboard. I then added the tablets and swiftly closed the door. After an hour, I grabbed my respirator, and opened the backseat, removed the container and then started the car putting the vents on recirculate to be sure I got it all. I let it run for 20 mins. Once the timer was up, put the respirator back on, turned the car off, all the windows open and let the car air out. The outside temp was hovering around 60 with a nice gentle breeze. The car has a smell of a pool. It's not strong at all. Just a faint smell that is refreshing in a sense. I'm pretty sure after a few days, the smell will be non-existent. I am so incredibly pleased with the outcome and I won't hesitate to use in other applications. I'll even consider a smoker car again since I now feel I can get the smell completely out.

EDIT: The product is not faulty just because you didn’t use it correctly. If you used half a bag it makes absolutely no since to return to the area 20 minutes later. Also it’s gas. No closing a door won’t contain it. The package says let it work a few hours at minimum. Use it when you can leave the house for a few hours. I bought a house and the previous owner didn’t disclose they had a pet. Apparently it peed everywhere. The basement and an upstairs closet stank so bad. Especially when it gets hot. I cleaned, bleached, used enzymes primed the walls and nothing worked. The smell always came back. Anyway I found this followed the instructions and the smell is gone. Word to the wise. Use a mask unless you want to pass tf out. This stuff starts working instantly be ready to put it down and run. You will feel lightheaded if you breathe this stuff in. It’s strong af. I used it in the basement and could smell it all over my house when I came back a fews hour later. It smells like a swimming pool x100 Only issue it took forever to arrive after ordering. TLDR; This works

Great product! Less does more. Do not use more than recommended. The longer the treatment the better outcome. Minimum 24 hours for great results. This stuff is amazing.

This really works, but you need to use it properly. First off, it's a really big bag, probably can use for 10 times. I placed a small cup inside a bucket as I don't have a large enough cup, and placed it in the car. Followed the instructions, 60ml of water and 15 small tablets, turned on internal fan to max and closed the door. Came back 1 hour later, turned off ventilation, closed the door. Came back 2 hours after that and it's done. There's a lingering chlorine smell for around 1-2 weeks, just open the window a bit when you drive and you'll be fine. I don't have pets or kids, it's just a 5 year old car and I'm especially sensitive to smells. It removes lingering smells so the car smells like nothing now, works better than a proper car shampoo because it even cleans up the ventilation duct. You don't need to remove air cabin filter or etc, honestly what I described above is all I did. My car is in the garage so no sun during that period. It really works, I tried all others apart from ozone and they are completely useless as compared to this.

I laughed so hard reading the reviews for this product (sorry). This liberates chlorine gas (literal tear gas, as another reviewer eloquently put it) so you have to respect the danger of using this product and use the right precautions. I didn't have as much of a smell problem as others, it was just that the bathroom of the new flat I was moving into was kinda of dank and musty and I wanted to banish the smell. I threw a few of these in the toilet and ran the hell out of there closing the doors behind me. Came back the next day and everything was fine, it smelled like a swimming pool for a few days which I personally enjoy. All the dankness was eliminated. I'll try using this for spice/curry smells in my kitchen too. The nice thing about this is you get so many, you can get a lot of treatments out of it. If you're trying to do multiple rooms, you need to use PPE. Either do one room at a time and use the chuck and run method, or get yourself a respirator which can filter organic compounds. For the love of god, DON'T HANG AROUND TO "WATCH IT WORK" unless you want to simulate the police brutality experience. It worked in the toilet and sink for me, but if you're doing a bedroom get a deep bucket because it can foam over (I didn't hang around to watch, but I'm told this and have memories from chemistry in sixth form). Also don't drink it or inject it into your children. It won't cure autism, but it will cause an acute exacerbation of asthma or cause chemical burns if that's what you're into. Can't wait to use it again!

Works surprisingly well. Bought a car sight unseen from auction. Absolutely trashed inside from a chain smoker. I was in a pickle. Tried a bunch of things with no luck. Found this, saw great reviews so I bought it. The price was pretty high but it's basically a lifetime supply for you and everyone you know (unless you're a commercial user). I used double the prescribed amount (maybe triple?), dropped the tablets in water according to the instructions and sealed the car up for a day or more. I watched the initial reaction and yellowish gas was forming and coming out of the cups as I would imagine mustard gas might look like (I later found out pure mustard gas is clear). It DEFINITELY looked toxic so I knew it was probably working!! SIDENOTE: DON'T use this inside like in a garage. Quick Tip: If possible, use your remote start once the tablets have dissolved to circulate the gas around inside the car to get in every nook and cranny. Prep: Open every sealed space like the glove box, center console, move the seats so they will be exposed on all sides (not folded down for example), then Set your fan motor on max, set it to circulate around as many areas as possible (forward facing and feet for example, also turn on the rear vents if possible, AC or heat depending on your climate, and ideally turn on the circulate air setting (rather than fresh air). I was shocked to find that the smoke smell had been almost entirely replaced with the smell of a pool. I'm not sure how much of an improvement that was, but in the end it was really effective at removing the smoke smell. Weeks later as the chlorine smell faded, the smoke smell was significantly reduced. To be fair, I hadn't even cleaned the car at this point. A thorough vacuum, wiping down all surfaces (hard and soft) knocked down the remaining smell, and a final quick blast of ozone took care of it for good. Oh and I replaced the cabin air filter. So in short, Yes this product worked, surprisingly well, much better than I expected. Almost nothing works on cigarette smoke. The fact this had any effect is a win but it actually did a great job! There are a lot of cigarette smoke "elimination" products out there but I wouldn't say any work as well as this. If you've got a smokers car, or found a great deal on one, there is hope... this is your first line of defense. It may take additional work but this is a great start. I would highly recommend it! (plus it was super easy)

Very good and got rid of the stink in the vehicle

Although expensive and delivery time was a little longer than necessary it has been great at removing “boat” smells from my vessel.

I had tried everything to get the smell of vomit out of my truck bed trunk, and nothing even touched it until I tried these pellets! They definitely work! Unfortunately they leave a scent of their own, which isn't the nicest smell but much better than vomit 😂
