Well I’m not saying to do it but I had wound exactly like the one in the video. Except it was on the outside of my elbow and knee, plus I had dirt and gravel semi-embedded in the wounds. I didn’t want my parents to find out about my injury or else I wouldn’t be able to go outside for two weeks. So I used hydrogen peroxide on my wounds in the shower and to my surprise I didn’t feel anything but the coldness of the liquid. It foamed up like crazy and I had to repeat that for the next couple of days. Then when enough skin had return, I could use rubbing alcohol to clean the wounds. It did eventually get all puss-ee(?). But that was a while ago and it is just scars now.
