I'm not sure how ice and water from melting ice combined with "driving over bumpy roads" does anything but waste time and money - and ice better used to chill beer. When you clean something, you are using an abrasive and scrubbing it, and the resulting friction helps to clean the surface. I don't think there is much friction created by slippery ice running over the surface of hard poop. And if you put lots of ice in, it won't move at all. I'd take the advice above and soak it. Clean it with the wand and repeat if necessary. You can get a clear elbow to check the color of the water coming out.
Good luck!
"Good tip" to see if there is still more stuff to come out and to continue filling and dumping until it runs clear of the stuff.
