I used this product on my light colored mare for cuts & scrapes. Although it worked ok on the scrapes (nothing special), it WILL NOT come off! I have tried everything to remove it to no avail. It has left crusty hard residue on the areas that were sprayed. My horse now has large dark, DIRTY looking spots all over her and no amount of washing with shampoo seems to phase it. Unfortunately, I would not EVER use this product again.
