hey elevenpoint i usually find a good toothbrush and put all of my roots in the sink full of water. Then i just take the brush gently over the roots only getting out the bigger pieces of dirt. Don't get them to clean they like to show the dirt in the rings. And don't make them smooth. Then i let them dry on a paper towel and put them up to dry. I hope this helps you. Oh yeah don't forget and use the wrong toothbrush.
