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.
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.
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.

And last a lot longer… probably.
Bottom line, no, I’m not washing feces in my dishwasher, period.
