I just used my normal bath soap, no special anti-bacterial cleansers....I took a shower before I took out my stitches and made sure I was nice and clean...sterilized my tools, and then put some vitacilia (the ointment we get in mty) afterwards.
When I had some of my stitches taken out at Kaiser, they used betadine to scrub my incisions before and then used some wound care saline solution wash afterwards. It seemed like overkill, but hey, I felt pretty safe lol.
Before you go under for surgery, you get a nice scrub down with betadine haha - im sure a very fond memory for most :)
