ODOR-CLO2 Chlorine Dioxide Odor Removal

It removed the odor from my car but the chemical odor took several days to dissipate. I followed all the instructions very carefully and aired the car out as instructed. I even had a high powered fan placed in the car. In addition I left the windows down overnight for several days. The product works as promised but be aware of the lingering chemical odor and possible throat and nasal irritation.

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)

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.

Works well. Don’t over do it it will explode. Smells like intense chlorine but eventually evaporates. Get a mask if you’re not ready to run out of the space, if you intend in setting multiple zone get yourself a decent mask with filters. You will thank me. FOLLOW DIRECTIONS!
