Tough # urine, # manure or # clay # STAINS??? So often I see that deep yellow or red and feel so bad. Why? Because, I can tell they TRIED SO HARD. But, in my experience washing lots with conventional soaps and #horse #shampoos can drive stains deeper. As the hair is stripped and gets dried out, it is more porous and stains lock in. Add typical stain, shine and/or detangling products, and hair discolors even more. Of course, a dirty stall leaves the horse no choice. Nonetheless, that cycle of one perpetual pesky stin can be broken. I promise.
