I laughed at your post.
Usually it was straight alcohol at our house or the purple stuff we put on the horses and cows.
We had these steel cups for pole vaulting that had torch cut edge on them. Somehow I slipped on one of these things bare foot and peeled the ball off of my foot at school. Alcohol and a bandage was all it got. Still got the foot. Ball and all more than 50 years later.
