Yesterday I used one of my new sheepskin wash mitts while washing. After I was done washing the mitt out, I grabbed it by the thumb and fingers pockets and slung it back and forth to get the excess water off before putting it up to dry. Well during the slinging it fell out of my hand and landed in the yard. I washed what I could off of it, but I am conserned that there's dirt embeeded in the mitt that I cannot see. I hate to throw it out after only one use, and I'd like to be able to clean it if possible. What's a good guaranteeed way to get sheepskin washmitts completely clean without ripping it up to pieces?
