We live by muck farms so our pasture is black dirt. My mare has a area where there is black it looks like dirt but it won't come off. How could I get it out? I don't want the judges to mark me down because if it.
I would try some Cowboy Magic green spot remover. It works great on manure and grass stains. I would think muck type dirt would be similar.
Are you in Michigan? Only place I have ever heard the term "muck farm"
