Wiped down?

In the craven silence book, I just came across a passage where it claims that JB’s lower body was “wiped down”. But it doesn’t say with what? Water? Soap? We know she urinated on the carpet and was moved. Maybe to clean up the pee? Or maybe to clean off something left on her like evidence. Anyone heard about this wiping down of the body? To me this speaks to the stager being someone that cared about her dignity a bit. They also took the time to cover her too. Makes me think only an adult would think like that. I’m leaning towards Patsy as the stager.
