Wait...that may be a little difficult. They are disposable. They break down with the application of liquid and tend to soack up fecal matter.
I would strongly suggest against reusing anything that gets smeared with feces. Your poop carries many harmful bacteria and even if it looks clean, chances are those bacteria remain after a wash.
I’ve been down sewers and have seen first hand how wet wipes and “rags” clog up the system. It’s pretty gross truth be told. Strangely frogs LOVE it and breed like crazy down there.
