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?
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.
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.
Thanks! This seems like it’s the best solution for my problem, maybe both of them.
Came here.to say this. Also, if bleach won’t damage it, bleach is good.
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.
Bleach doesn’t really work with urine… I’ve tried.
It really needs an enzymatic cleaner. Which I tried after the bleach.
Now that works
Omg the smell from heating it…
Do I even dare to ask why you need to know this?
Use it white wine vinegar to clean it. Vinegar denatures urine.
Sure, but then dude has got little dentures rolling around in there. And that won’t help.

Whatever you decide, please wear an N95 mask while cleaning - en.m.wikipedia.org/wiki/Orthohantavirus
Probably the same temperature as mouse. Some of them solids don’t cook off.
Since you mention this is a vehicle, I think the ozone generator approach is probably best.
I’ve had vehicles with similar issues, and open windows + time really did it. An ozone generator is the faster version of what I’ve done.
Just don’t let it go crazy, as ozone attacks pretty much most materials in a car. So maybe throw a generator in it, let it run for a couple hours (put a small fan in the car to really circulate it up under the dash), then air out the car well.
The idea is the urine is probably more reactive to the ozone than anything else, so get it reacting. Then stop and clear the air before it has too much time/concentration to start on the plastics.
So I had a similar issue in the past that I used an ozone generator for… all of my upholstery just unglued itself. So this is one of the solutions that has been suggested among “just torch the thing and collect the hefty insurance on” that I am trying not to do lol… but enzymatics have been suggested elsewhere and apparently have come a long way. That’s definitely my next try.
ozone is an oxidizing agent. it destroys smells by oxidizing the proteins and such that create the smell.
Unfortunately, this also means that any plastics or adhesives used will generally be broken down too. (the degradation in plastic is similar in effect to UV exposure, where the adhesives just… as you mentioned… becomes ‘unglued’)
Enzymatic cleansers will likely be a better solution. Though, I’ve used ozone generators to remove some truly… unique… smells; when I was working for a college cleaning dormitories. but it really is a nuclear option.
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 psuedomonas to eat it and turn it into ammonia. It technically starts vaporizing at above 130 C.
Most ducting in the dash of vehicles can be accessed with just a screwdriver, and there are usually only a handful of screws and plastic fasteners/snaps you have to remove. Downloading the diagram from a shop manual will show you where they are so you don’t have to find each of them, but it’s usually apparent in situ.
If you don’t remove the ducts to clean them, while you may be able to lessen the smell by removing vent covers and snaking cleaning materials through the ductwork, your car will still always smell. The only way to get rid of the smell entirely is to remove the affected ducts and properly wash them.
Before any if that, however: do you know which ducts are affected? It will reduce your workload considerably, especially if the affected duct is in fact your fresh air intake, as I would expect.
The way I would determine that is to
In that case you’re in luck, as you may not need to disassemble the dash much at all. (You would be working mostly in the engine compartment and passenger footwell.)
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
This is one of those oddly specific questions that makes me think “Dude, I’m not doing your homework for you.”
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 some part of a car in a microwave 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.

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

Definitely, a faux pas. A correct answer would be: “try it, film it, share it.”

Like that guy that posted photos of him electrocuting his testicles with a car battery to prove it wouldn’t hurt?
