Up date for your interest. Yesterday I bathed the pigs!
they were covered in mud and pee after weeing in their wallow. They came up a treat, and smelt lovely. I used a mitten loofah and a bucket of warm water both loved it and tried to drink the soapy water from the bucket.
It was short lived, this am they had both been in the wallow so now smell just as bad!! but would def do it again.
Could advertise as soap to use b4 a show as I know people wash/bath them in preparation for a show.
