My story Just got rid of all 4h projects in the barn and need too get ready for new cattle coming in. My question is I had a touch of ring worm in the barn what should I use or do I need too do to starilize the barn. Now before you go crazy with the wording I am using the word sterilize loosely! I dont think my would barn can be starilized, although is their a solution I might spray or pressure wask walls and wood fencing with that might killany fungus or problem bacteria.
