Back in the day my mom used kerosene on our cuts. Must have worked.
My dad was a butcher and his hands were all scarred up from knife cuts. His "old fashioned" remedy...he was born in 1892...when he got a serious cut was to get a piece of waxed paper, put a couple tablespoons of sugar on it and moisten it with enough turpentine to make a paste, then apply paste to wound. It would heal up quickly with no infection, although it probably stung like a sumbitch on a fresh cut. Fortunately I didn't ever get a serious enough cut to get "treated".
