1 cup mud (such as Ice Tight)
1/4 cup Iccathamol
2 TBS Epsom Salts
1 tsp alum
You don't necessarily need the alum.
THIS...it'll suck an Elephant thru a keyhole, even without the Alum. I had no idea what that was so I mixed the other products and 12 hours later we had a sound pony with a very stinking hoof wrap! Sometimes I can't get the ichthamol to spread because of the cold and I have used Iodine instead.
I am trying this tonight if the one in my guy's foot still hasn't busted today. He had an air pocket back by the bulb of his heel last night, so it's gotta be close. I'm assuming it works even if they are coming out the cornett band? Do you slather the whole foot or just the area if you know where it's at?
Tide with Bleach Laundry Powder. A cup in a gallon or so of very warm water. Soak foot til water cools. I've always had success with this, though not overnight.
