Had it before from a r&t place. I think they were busy so used a cold dirty towel instead of a clean hot towel. (Not Cool)
In the end, apple cider vinegar worked, stung a little and took consistent/multiple applications and lots of prayer for nothing worse. Also, similar to the above, used some strong medical grade anti-microbial soap. In the end, some light scarring that pretty much faded out with time.
