As I remember. They had me report to the hospital ward where I 'd be sent after the recovery room and had me shower in an empty hospital room. This was 30 plus years ago, so obviously procedures have changed.
If they are less worried about infectious disease precautions today, I may as well just use the half bottle of a disinfectant mouth wash they gave me after an oral surgery procedure in June to save a failed root canal to disinfect my knee. That has chlorhexidine gluconate in it, too.
