Ew... like, all alone, with nothing else in the dishwasher at all, and a rinse cycle in-between that and other things that you plan to eat off of?
Even then, it seems inefficient to me. Also, why would those even need to be cleaned - do you plan on eating off of those?!? They get "cleaned" well enough by going into the toilet - no need for more?
Usually I clean the toilet with soap and the brush, and then occasionally clean the brush by cleaning the toilet like normal, flushing, and putting a stronger antimicrobial (looks like bleach but isn't, since they don't sell it as much anymore due to the danger it has around the house) on the brush and then rinsing it in the toilet and flushing again.
Mostly I don't want it to stink. It's bad if anyone has cause to notice the toilet brush tucked almost behind the toilet. Same for the plunger.
Meeh, I do clean them from time to time. They do become very dirty after a while and it shows since they're white. Not really often, like once a year, but still.
You take the bowl in which it resides, you clean that with... whatever, soap, shampoo, dishwashing liquid. Use a dish sponge from the rough side, gets the best results 👍. Then, you fill that up with some hot water and pour some soap/shampoo/dishwashing liquid in that and start stirring that with the toilet brush, just grinding it in there. You do that for about a minute, it should be shiny as new.
You take that shit back right now or Ill wash your mouth out with an uncleaned toilet brush!
Skibidi Toilet is fucking brilliant for what it is. Its like an abstract arthouse scifi film made with free tools. It somehow made me laugh, cheer and feel creeped out. Ive seen worse content made by serious movie studios. Its amazing to watch the whole.thing and see the creators skills come along throughout.
