    Default Mold abatement, have you used ClO₂ ? It may be the stuff

    Doing my homework on mold in a vessel, I came across this. Been reading a number of pages on it. Anyone familiar?

    A powerful selective oxidizer, Chlorine dioxide (ClO₂) is an exceptionally effective and versatile yet low toxicity odor, mold & smoke eliminator.
    Only ClO₂ may be generated and used as either a ‘gas vapor’ or ‘liquid’ in the atmosphere and on non-porous & porous surfaces.

    Will neutralize & eliminate


    • Mold, Mildew, Fungus, Algae
    • Embedded Smoke & Food
    • Pet, Dead Animal & Rodent Odors
    • Urine, Vomit & Garbage
    • Chemical & Masking Agents


    You can use it like a liquid to wipe down surfaces, or set up a vapor to permeate all the unseen nooks.

    I intend to vapor bomb my boat, has anyone else tried this stuff?

    I'm not sure you would want to use chlorine dioxide vapor. According to the Wikipedia article:

    "At partial pressures above 10 kPa[13] (or gas-phase concentrations greater than 10% volume in air at STP), ClO2 may explosively decompose into chlorine and oxygen. The decomposition can be initiated by light, hot spots, chemical reaction, or pressure shock. Thus, chlorine dioxide gas is never handled in concentrated form, but is almost always handled as a dissolved gas in water in a concentration range of 0.5 to 10 grams per liter."

    And if you're going use a liquid, why deal with chlorine dioxide - why not just use sodium hypochlorite (i.e., household bleach)?

    There is a lot of stuff on the web about how great chlorine dioxide is as a disinfectant, but as far as I can see most of it is posted by people who sell chlorine dioxide.
    I will beg you for advice, your reply will be concise, and I will listen very nicely and then go out and do exactly what I want! (Apologies to Lerner and Lowe.)

    I work with chlorine dioxide as a gaseous bleach for stain removal on paper. The single advantage being the item doesn't get wet. It works, it bleaches it kills mould and bugs. It is generally considered to be a last resort, never, ever used unless inside a fume cupboard and the fume cupboard has to have hazchem status, not just an exhaust out of the lab into the outside world, but full filtration. at the concentrations we use it is effective. but considered potentialy highly toxic.
    At 'safe ' concentrations it was absolutely no more effective than as above, Sodium hypochlorite. household bleach . or any other oxidizing agents, potassium permanganate, hydrogen peroxide. If you really need a killer hit use swimming pool grade NaOCl, crystals or buy it ten molar liquid from a Pharmacy, agroproducts store etc.
    NaOcl and Cl02 release chlorine gas on contact with acids . Not pleasant and of course fatal in high concentrations.

    I wouldn't dream of using it in an uncontrolled 'vapour bomb my boat' situation
    If my eyes don't deceive me, there's something going on around here

    So I'm a bit perplexed. The warning you both give, I do not see in my homework. Are we referring to the same thing? Please check this item: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 Are you using higher concentrations?

    You need to do your homework better... https://www.sciencedirect.com/topics...odium-chlorite will explain the hazards of working with chlorine compounds once you understand what they've written there.

    Your link took me to Sodium Chlorite. Looks like nasty stuff. https://www.sciencedirect.com/topics...odium-chlorite

    From the same site I see Chlorine Dioxide has no warning of any severity. It has been in use industry cleaning for a long time. https://www.sciencedirect.com/topics...lorine-dioxide

    It's not like handling chlorine:

    It is ten times more soluble in water than chlorine, even in cold water. Chlorine dioxide is widely used by municipal water treatment facilities.The term “chlorine dioxide” is misleading because chlorine is not the active element. Chlorine dioxide is an oxidizing, not a chlorinating agent. ClO2 penetrates the cell wall and reacts with amino acids in the cytoplasm within the cell, killing the microorganism. The by-product of this reaction is chlorite, which is harmless to humans.

    What concentrations are you using for stain removal on paper? Everything I read there is no Hazmat warnings for ventilation etc.

    Just because you can buy it on amazon doesn’t mean it is safe.

    Thanks for that sheet. I donít see any warnings except for irritants.

    I just googled "chlorine dioxide". Sure seemed to be plenty of warnings on the first page. For example:

    People also ask

    Is clo2 harmful?

    Higher exposures can cause a build-up of fluid in the lungs (pulmonary edema), a medical emergency, with severe shortness of breath. * Chlorine Dioxide is a HIGHLY FLAMMABLE and REACTIVE gas and a DANGEROUS FIRE and EXPLOSION HAZARD

    "Not sold in Canada or Europe"...bit of a red flag (for me at least)

    This product reminds me of the old roach/flea bombs available when I was a kid, hold your breath, pop the can and run as the room filled with toxic fumes. I'm sure that didn't leave any lingering effect.

    I also wonder, once the toxic cloud has dissipated you still have all that dead mold (and anything else that got caught) does that not become food for the next generation?

    What am I missing here? It's being used by industry.

    https://youtu.be/DDxXyQuubHQ Everything I read this stuff is being used and sold to the general public. It never gets close to a dangerous mix. There is no way it would be available in all the big box stores if it was that volatile. It's no different than other chemicals you have to use as instructed.

    Thanks for the comments, it made me dig around. I report back on the results.

    Read and understand the whole sheet. If you like your corneas and lungs wear unvented goggles or better a full face shield respirator in inclosed areas. My working for over 30 years in the lab with hazardous chemicals say you should treat this with respect.

    Personally I'd try just increasing ventilation and possibly using borax.
