I’ve cleaned it twice just to feel good about it, but it’s been sparkling aside from some hard water deposits, which came off pretty easily. It always runs water over it after use, and the nozzle angle is so steep, it doesn’t get poo on it. I have a toto one. (I’ve had mine since about mid 2021)
I still clean the toilet seat and the underside of the seat though, which can get a bit of pee on it if you’re a guy. I’m a bit of a clean freak too, so when I say clean, I mean clean, lol.
