Sometimes when I have a particularly heinous dookie I’ll get in the shower afterwards, and I make sure I’m clean by actually wiping my hand across it to see if there’s still poo.
You can do the same thing with a bidet and completely obviate the need to get in the shower.
As I understand, those who clean with soap on the bidet are already washing the hand that washes out the ass-crack, the same way as if you’re in the shower, and now to know your ass is shower level clean.
You know you’re clean the same way you know you’re clean in the shower. And just like the shower, some use a bit of soap when using the bidet.
