The LakotaNaturals Clo2-20.10 is a chlorine dioxide-based odor eliminator designed to tackle the toughest car smells. Marketed as a “car bomb deodorizer,” it targets stubborn odors from cigarette smoke, spoiled food, mold, and pet accidents that survive standard cleaning methods. If you’re dealing with a persistent stench in your vehicle and have tried everything from carpet shampoos to professional detailing without success, this product is positioned as a last-resort solution. Our bottom line: it works remarkably well on severe odors, but expect a temporary chlorine aftertaste that requires airing out.
This compact 2-ounce container uses chlorine dioxide gas to chemically neutralize odor molecules rather than merely masking them. The application is simple: activate the product, place it in the affected car, close the windows, and let it work for several hours. Users report dramatic results against smells that seemed permanent, making it a valuable tool for anyone buying used cars or dealing with accidental spills. However, the strong chlorine scent left behind can take a day or two to dissipate fully, so patience is required.

Design and Build
The LakotaNaturals Clo2-20.10 comes in a simple, compact plastic container that holds 2 ounces of active ingredients. The design prioritizes functionality over aesthetics: there are no sprays or nozzles. Instead, the user opens a sealed packet or container (exact method not specified, but typical for chlorine dioxide bombs) to release the gas. The small size makes it easy to store in a glove box or trunk for emergency odor removal. The packaging is minimal, with instructions likely printed on the label. While the build is basic, it serves the purpose of a single-use or limited-use treatment product.
Performance and Features
How Chlorine Dioxide Works
Chlorine dioxide (ClO2) is a potent oxidizing agent that reacts with odor-causing molecules, breaking them down at the chemical level. Unlike air fresheners that simply cover smells, this compound neutralizes them. The gas fills the enclosed space of a car cabin, reaching into fabric, carpet fibers, and HVAC vents (though the manufacturer does not specify coverage area). The product is specifically intended for automotive interiors, where its gas can penetrate deeply into porous materials.
Application Process
Users describe a simple set-and-forget process: activate the product (likely by breaking a seal or mixing components), place it in the car, close all windows and doors, and leave it for several hours. Reviewers report using it for 2 to 15 hours depending on odor severity. Afterward, the car must be aired out thoroughly to remove the residual chlorine smell. The product is not reusable; each container is meant for a single treatment.
Effectiveness on Different Odors
Based on customer feedback, the LakotaNaturals Clo2-20.10 excels against strong organic odors. One user eliminated a sour milk and moldy bread smell that survived a $200 professional detail. Another removed cigarette smoke odor from a 2016 car completely, even without changing the cabin filter. A seafood spill in a Volvo was cured after other methods failed. However, a musty smell from a wet carpet was only reduced, not entirely eliminated, suggesting deep-set mold may require multiple treatments or additional steps.
Maintenance and Running Costs
This product is not a long-term maintenance item but a one-time or occasional treatment. There are no filters to replace or ongoing costs. The 2-ounce container is used in a single session, so the cost per treatment is the purchase price. For severe odors, you may need a second application, as noted by one reviewer who felt another round would finish the job. There are no accessories or replacement parts required.
What Owners Say
Owner reviews paint a picture of a highly effective but not miracle-working product. The rating distribution shows 65% five-star, 11% four-star, 7% three-star, 5% two-star, and 12% one-star. Positive reviews often describe it as “amazing” and “unreal” for smoke and spoiled food odors. Several users noted that the chlorine smell fades over a few days, leaving a neutral or “new car” scent. Negative reviews appear to be rare but may involve less severe odors where other methods might have sufficed. One detailed review mentioned the chlorine smell persisted for two days and the musty odor was only slightly reduced, indicating that very stubborn mold might require repeated use.

Who Should Buy It (and Who Should Skip It)
Buy this product if you own a car with a persistent, strong odor that has resisted conventional cleaning. It is ideal for used car buyers, pet owners, or anyone dealing with smoke damage, food spills, or mildew smells. If you have already tried vacuuming, shampooing carpets, and using spray deodorizers without success, this chlorine dioxide bomb is worth a shot.
Skip this product if you are merely looking to freshen up a clean car or mask a faint odor. The temporary chlorine smell and the need to leave the car sealed for hours make it inconvenient for routine use. For lighter odors, consider a traditional air freshener or an air purifier with an activated carbon filter. If you struggle with indoor air quality at home, our indoor air quality tips may help.
Final Verdict
The LakotaNaturals Clo2-20.10 fills a specific niche as a heavy-duty odor eliminator for automotive use. Its chlorine dioxide chemistry delivers real results on smells that other products cannot touch, as confirmed by numerous customer success stories. The simplicity of use and compact size are practical advantages, though the lingering chlorine odor requires patience and good ventilation after treatment.
We recommend it as a last-resort tool for any car owner facing a truly nasty smell. Just be prepared to air out the vehicle for a day or two. If you are also concerned about allergens or airborne particles, pairing this odor bomb with a quality cabin filter or a portable air purifier for allergies and pets can help maintain a fresh interior long-term.
FAQs
How does the Chlorine Dioxide Car Bomb Odor Eliminator work?
It releases chlorine dioxide gas inside your car, which chemically oxidizes odor-causing molecules rather than simply masking them. The gas penetrates into fabrics, carpets, and vents to neutralize embedded smells like smoke, mold, and food spills.
How long does the chlorine smell last after treatment?
Based on user reports, the chlorine odor typically fades over one to three days with proper ventilation. Rolling down the windows and parking in fresh air speeds up the process. The smell is temporary and eventually disappears completely.
Is it safe for my car’s interior?
Chlorine dioxide is generally safe for automotive materials when used as directed. The manufacturer does not specify any warnings about damage, but it is wise to avoid contact with sensitive electronics or leather surfaces. The gas is non-flammable and evaporates without residue.
How do I use the product correctly?
Activate the product according to the package instructions (typically by removing a seal or mixing components), place it on a flat surface inside the car, close all windows and doors, and leave it for at least 2 to 15 hours depending on odor severity. After treatment, air out the car thoroughly before driving.
