Okay, if everyone's too scared, I'll just say it: in scientific terms, this is called a fixed-point operation. The operation is performed until a fixed point is reached, meaning further operations will not change/affect the state anymore. The moment your wipe is clean, means that you didn't affect your ass anymore, hence a fixed point is reached. That's the signal that you're done. 🤓

It takes one spray to know you need zero wipes. #BidetLyfe
