""mineral salt (the orange/brown salt available from farm supply stores - it's used to feed to livestock)." No one has ever shown there is any benefit from putting salt (of any kind) in grease patties. There is lots of evidence that plain Crisco and sugar is very effective against Trachael Mites. Add 1/3rd cup of sugar to 1/1/4 cup Crisco (melted) to make one patty and replace as necessary. Lloyd Lloyd Spear, Owner Ross Rounds, Inc.
