Originally invented for foal's diarrhea, it's the best product I have found so far for horses with fecal water syndrome or loose stools.
Just spray it on twice a day without washing off the manure first, and see how it magically falls off after a short while.
Perfect to use when it's too cold to bathe or when you are at a show and have a nervous horse on your hands.
I tried it over the winter on my retired paint gelding with chronic diarrhea who gets sores from all the scrubbing. It worked like a charm and his hind end looks cleaner and healthier than in a long time.
