You don't put it in the water. It's kind of like a goo...or gel. It gets really slippery when warm and makes the gunk/dirt slide off your horse easily. There's directions on the bottle. Some people use a rag. I've heard of people putting their hand in a tube sock for easy cleaning. Of course, with a mare, the job will be a little easier. You just rise it off when you're done and it's okay if some stays on (unlike soap).
