160F/72C - s'pose it depends on the machine. It's not the sort of bacteriologic roulette I would want to play. Truly a 'shit post'. Er, Bravo, I guess.
I believe most of them have a setting where they can sanitize things, because it’s a function of not just temperature, but also time.
Commercial dishwashers do the same thing much faster by using higher temperatures, but they also tend to get to sanitary, not sterile which needs higher temperatures for a longer times.
Use the sanitize and steam settings, tho that might melt the shitty plastic on most toilet brushes… But at least you don’t have to worry about living bacteria
Not gonna lie your sister might have some mental illness, let’s consider for a minute that the dishwasher might be very very good at cleaning I still would never do this due to the gross factor. Sorry mate but I’m not gonna put anything that goes in the bathroom anyway near things that food goes on to!!
Maybe, just maybe, something which was designed to kill the bacteria and remove the residue of things that came in contact with fresh or at most rotten food, is also totally effective at doing the same for things that came in contact with fecal mater and with toiled cleaning chemicals. Or maybe not.
Do you for a toilet brush need the level of cleaniness achieved by a dishwasher, and if not are there other reasonably simple methods to achieve the required level of cleaniness for it?
In the absence of actual scientific studies that provided an answer for the “is a household dishwater entirelly effective for fecal mater and toilet cleaning chemicals contamination” question with a high degree of certainty, the consideration on whether to do this or not boils down to: “Is a dishwasher level of cleaniness for a toilet brush worth the risk that the dishwasher might not deal with fecal mater or toilet cleaning chemical contamination correctly?”
Here is another reasonable approach which is simpler. Isolation and containment is the best way to prevent spread of bacteria from one place to another. Minimising taking any items from the toilet to the kitchen, minimises the spread of bacteria between the two places.
So without any scientific study or evidence specifically to dishwashers and toilet brushes, we can make a reasonable assumption that taking a toilet brush from the toilet to the kitchen is a bad idea and should be avoided.
I doubt this is real, but if it were and I were the poster I would also isolate and contain that home. I would erradocate the movement of me from any other location to that home.
I mean… that’s putting a lot of faith in the dishwasher to work properly every single time you do it. I don’t know if I’ve got enough trust in the 1995 beige “landlord special” under my counter right now.
It’s supposed to get hot enough to kill. You’re putting a lot of faith into a machine that doesn’t get much maintence done on it.
If my dishwasher does not heat sufficiently, it may take me years to discover that with no ill effects to me.
If a poop dishwasher is not heating correctly, it may take them many rounds of illnesses before they connect the dots. That is because they’re putting poop into the dishwasher which sprays liquefied poop onto all their dishes and flatware, but never sanitizes anything.
Tldr, don’t put poopy objects into the dishwasher.
I mean, if a household that keeps kosher has two sets of everything (plateware, silverware, sinks, etc) to make sure meat doesn’t touch dairy…the logic states you should have a different machine/method for excrement-related things to ensure it doesn’t touch your normal plateware and silverware.
I, personally, would not be comfortable using the machine again for food related things if I found out my housemate had washed the toilet brush in our dishwasher. Poop is meant to be expelled from your body, not consumed in any way - may I remind (the royal) you how pink eye originates?
I’m not proud of this, but I need to ask. My sister insists on cleaning the toilet brushes in the dishwasher’s top rack, and I have reservations. To me, it doesn’t seem very sanitary. Thoughts?
They’re still not the same germs. No dishwasher goes over 90 or 95°C (household ones). There is bacteria in feces that can survive that temperature. Not to mention parasite spores/eggs, some can easily withstand even 150°C.
How did steel and aluminum parts react after coming into contact with hot water and soap? I can imagine a non-trivial amount of milling/resurfacing of any interface that is meant to take a gasket due to how metals react to caustic environments.
Unless you disabled the dishwasher’s internal heating element and used degreasers instead of water… that makes a lot more sense.
I work in a production line that makes parts for diesel engines. We wash the parts in water and alkaline solution, then they hit a drier and get dried. Basically a giant dishwasher. The company is multi million dollar and world wide.
Just a long winded way of saying your imagination is wrong
I just used dishwasher tablets and It was fine as long as you took the parts out straight away while they were still “you need gloves” hot and hit them with WD40 or sat them in the sun. Never had an issue so long as I did that.
most dishwasher detergent formulations contain corrosion inhibitors for steel, some even contain corrosion inhibitors for aluminium though those are usually in the upper price segment.
The bare aluminum became discolored, rough and ugly. Food sticks to it more, requiring more scrubbing to clean them. I dont know what that reaction is from a materials science perspective, though, if thats what you’re asking.
You guys arent talking about aluminium thats been under the hood of a Honda Civic for 25 years, heat cycled literally thousands of times and covered in all manner of filth.
IF your dishwasher is working properly then you ought to be able to put your poop knife, dinner dishes AND toilet brushes in and everything comes out sanitary.
Don’t ask why there is peanut butter left on the knife. You’ll be ok.
Yeah I was gonna mention that I don’t think the soap and steam really care if it’s poop germs or food germs. As long as your dishwasher is working properly, everything in there should be snapped out of existence.
Seriously just make sure the peanut butter is rinsed off beforehand.
My brother in Christ it’s still extremely hot steam and soap. I didn’t mean they’re the same kind of germs but they’re germs. High temperature and soap kills them because if they didn’t I got bad news for the dude who shit himself and tried to shower. My point was they all die.
Well, it’s a hospital. They handle a lot worse than poopy bacteria. Just because carpenters bring a nailgun that doesn’t mean a hammer isn’t nearly good enough.
This isn’t true. A generic dishwasher for at home is not up for the task. Even the stuff they use in restaurants aren’t up for the task. And they already wash with boiling water. Despite this, there are always leftovers. I had the task of cleaning these things at a maccy Ds. Found pink mold that thrived in coffee grounds to survive the dishwaser perfectly. Like the pink goo from the teletubbies.
Yeah, you need a dishwasher with a proper sanitize cycle. Most residential dishwashers, even some with an alleged sanitize cycle, aren’t up to the task. This is why laboratories will pay top dollar for an industrial dishwasher that looks nearly identical to a residential version but it actually will sanitize its contents.
Oh totally. If I had a dedicated shitwasher, sure, but not in the dishwasher with my dishes and utensils. I’m a microbiologist so I’m pretty cavalier about my everyday microbe exposure but that’s a really bad idea.
Try and explain to some people here that not all germs are the same and not all germs/parasites get killed at 90 or 95°C 😒.
Dedicated dishwasher (which I would never buy, since I wash those things like once a year), sure. But, hotels doing that, yeah, I can see it and there is nothing wrong with that, as long as they’re done separately in a dedicated one.
Holup, you raise an interest point. A true sanitize cycle is heat. It gets hit enough to kill everything.
How the fuck is a plastic toilet cleaning brush surviving the level of heat sufficient to kill all bacteria?
If the original dishwasher from the past for got enough to kill bacteria, the brush couldn’t survive. Therefore, the dishwasher isn’t getting hot enough to kill bacteria. Therefore don’t put poopy plastic into your dishwasher!
So what we’re looking at is sanitize vs sterilize.
A sanitize cycle typically gets the temperature of the water up to about 65-75°C and holds it there for at least 1.5 hours. This kills the vast majority of pathogenic microbes as human pathogens typically live at around human body temperature. You’ll see ads on how this cycle kills 99.999% of microbes, but the fine print typically states something along the lines of “foodborne microbes” or “pathogenic microbes”. Anything outside of that may survive, especially if it’s a species that forms endospores or a toilet brush.
Sterilizing by definition kills anything living and deactivates viruses. You won’t get sterilization by heat in any dishwasher, which is why laboratories and medical facilities sterilize with an autoclave. An autoclave utilizes pressure to raise the water temperature up to around 120-135°C without it boiling. This still won’t sterilize everything, particularly the aforementioned endospore forming bacteria, but it’s functionally sterilized for most purposes. For true sterilization, certain autoclaves can reach much higher temperatures and pressures, in excess of 600°C and 0.5 GPa, respectively, which obliterates fairly well everything, but those are extremely uncommon and for niche uses as temperatures that high may just melt your glassware.
This is the same sort of reason why you can’t 3d print items that will come in contact with food. 3d printing leaves microscopic holes in the surface of the object, and once food gets in there, it’s never coming out and will become a breeding ground for all kinds of nasty stuff.
I worked at a restaurant in the kitchen. We had a place on the wall to hang brushes. The GREEN brushes were to be used for food/prep areas only. The white brushes were for cleaning toilets, and other filthy places.
The white brushes were soaked in buckets and rinsed/washed thoroughly in a slop sink, then later, put in the racks that push through the dishwasher conveyor belt that ran through the machine if I recall correctly. It’s been more than 20 years
See, this makes sense to me. It’s the same way with anything IMO. If it involves bodily fluids, beyond native saliva and tears, you probably want to wash it specifically. At least in its own load, possibly in a different machine entirely, maybe even get it professionally handled, or clean it with fire. Depending on the severity of the soiling…
I have no issue with someone using a thing that was designed for another purpose to do something that it’s designers didn’t think of. As long as you’re not cross contaminating your food with it, I couldn’t really care less… But bluntly, using your dishwasher, the same one you use for dishes, to clean your poop scrubber? Big nope from me.
