Let’s say I hypothetically had some mice pee in some plastic components that cannot be properly cleaned in any realistic way. Is it possible to heat it up to “cook off” the mouse pee nastiness without actually melting the plastic?

    perhaps I’m committing some well known Internet discussion faux pas, but whatever you’re trying to do is probably not going to work.

    It depends what you mean by nastiness. Doesn’t urine contain salts that you’re never going to realistically boil?

    While urine doesn’t typically contain large amounts of protein, it may be present along with other metabolites that I don’t expect can be boiled.

    Uric acid and urea can be boiled off over about 200 Celsius, but you are going to have residue remaining.

    Get some enzyme spray specifically for addressing pet urine. There are lots of varieties online from pet warehouse places. Nature’s Miracle is a popular one. Get the urine destroyer, the stain and odour eliminator isn’t as good.

    It actually breaks down the urine residue as opposed to the other suggestions here which mask or encapsulate the smell without addressing the source.

    I have used enzyme on quite a few things I thought would never be usable again - def worth their weight in gold in my experience.

          It’s more about It’s ability to move fluidly (gasously I guess…) and interact with anything else that got itself caught up in the plastic ductwork of the vehicle, other things in the barn I have more time. But spring is upon me, and it won’t be worth fighting over this if I can’t get it to not smell so ridiculous.

    I think it depends on what you’re going to use the plastic component that were sullied for.

    Food Tupperware? You’re SOL. It’s porous and now contaminated. A plastic computer component? Disinfect it with diluted bleach.

    I’m not sure heating mouse urine is a good idea, it certainly won’t smell pleasant, I can tell you that.

    Use white wine vinegar to clean it. Vinegar denatures urine. Then wash again with soap and water to get rid of the vinegar smell (if necessary).

    Edit: also good for getting out the cat pee smell from when your cat decides to get back at you for whatever you did to piss it off.

      It’s two separate questions I guess, where the answer, would answer both.

      As for the more pressing issue. It’s inside some automotive internal stuff, that just wouldn’t be worth the time or expense to remove it. I really want to retain the vehicle for limited use cases, mice no longer are in the vehicle, but the odor is bad.

      I don’t necessarily expect to eliminate the odor 100%, but any reduction to the point where you don’t feel like your breathing in some measuruable amount of mouse urea would be nice…

        Look into ozone generators or ozium air fresheners. Ozone generators sanitize without heat and help reduce odors but might be expensive and take a long time to be effective (hours to days). Ozium air fresheners absorb the odor and they got the gasoline smell out of my car, no idea how they work but you just leave them in your car.

        So, I have no clue what exactly it is that you want to heat and how you would do it (I somehow imagine you trying to put a microwave over the steering wheel of a car or blow drying your radio) but as for whether it would work to eliminate the odor that is bothering you… I am no expert on mouse urine smell but I did work with GC and judging from GC-O measurements you need to go up quite over 100°C to make every molecule that gives off smell volatile. So my guess would be, no, you cannot cook off the smell. My guess is even if you literally boiled a cup of mouse urine for an hour on a stove and let it cool down it would still have some odor left.

        That being said, I very much hope I am wrong and you or someone else will prove otherwise!

        The way I would go about it is probably to use something like Febreze, basically trying to put the odor molecule into a complex (is this how Febreze works?) where it either cannot bind to your receptors anymore or isn’t volatile anymore. Probably do all of it, first blow dry (?) and heat off what you can, then use some H2O2 spray if the plastic allows it first (might even get some stuff to oxidize and change its properties i.e. the smell), then blow dry (?) it again to heat off what you can, then use an odor neutralizer.

          Lol, yall are really good at getting in my brain.

          So I basically have a very large tapered heat gun, with a fan… basically like a really dangerous blow dryer. I know from experience, that I can’t continuously heat in the same place (melts plastic, that I thought almost couldn’t be melted…)

          From your comment, and others, it seems like heat might not be the most ideal solution. It seems as if all this vents out to certain points that make sense, and have adequate airflow (no idea if this is actuality, taking it apart would take apart my week). So I could buy anything within reason, is febreeze the best solution if I went that route? I have heard of using “Ozium” instead or there is some kind of weird sugar type substance (can’t remember the name off my head) that was recommended that could encapsulate it?

            Lol oh Jesus please don’t use the heat gun (although I would love to use it myself), apart from the danger, I’ll also point out that while you might not melt the plastic, you might still destabilize it and/or release some actually toxic (and also smelly) compounds. I imagine a low heat blow with a normal hair dryer just to air it out would be a smart step though.

            As for what works best in terms of encapsulation - I would try to ask in a community of rodent lovers. I can imagine that those guys have their secret weapons.

              Haha thanks! I am at my wits end, and want this over before it warms up in my area. I was kind of hoping some chemist might come in and give some funky way to destroy the compounds. The solution can literally be the most crazy crazily toxic compounds… as long as in the end they all cook off and get rid of the mouse nonsense.

              I have access to money, chemicals, really strong fans and other equipment, and a lot of open air. Heat just seemed easiest, my chemistry knowledge is sophomoric at best.

                Came back to read the other comments, take the enzyme spray!!! I highly vote for the enzyme spray. If there’s an enzyme for your problem then always take the enzyme.

                Ozone sounds also really cool but keep in mind that ozone itself smells weird and maybe don’t exactly breathe it in. (The smell will go away fast but I have worked with quite a few people who felt quite lightheaded after breathing in the ozone from a freshly UV-ed workbench.)

                Whatever you choose, read the label instructions first to make sure it doesn’t corrode stuff, break down plastic etc.

    Definitely higher than the softening point of the plastic. What kind of parts? Car, residential appliance, etc?

      It’s a couple different things, but one of them is automotive plastics. There is just no way to get to parts without tearing the entire thing apart, and I don’t have the time or technical skills to do it quickly. And even if I did, I am not sure if it would really be worth it because of how infrequently it’s used.

        You might be able to soak it in some kind of water/soap or isopropyl bath and then dry it. If it has electronics it might not be doable without taking things apart

    You pretty much either put so much heat into urea that it turns to ammonia and melts your plastic while doing so or you wait for some bacteria to eat it and turn it into ammonia. It technically starts vaporizing at above 130 C.
