Hi Elle; If you have a
hot water high pressure washer it might do the job just fine. Make sure any solvent is completely flushed before using.
My other thought is are you sure you want to leave the skin on ? That is the traditional way of hog butchering, but...
It is my understanding, it was mainly done when pork was heavy salt cured and hung in a smoke shack. Some folks do prefer it that way.
Unless requested most butcher shops skin now.
