I have a Lyman 1200 Vibratory tumbler that uses only solid media. I use it very little.
My main tumbler is a Thumler's Model B rotary. It can use corncob/walnut media or water. 90 percent of my cleaning is done with warm (NOT HOT) water and liquid Tide.
20 minutes usually cleans anything. Of course, they must be dried. I put them on a cookie sheet and leave them in a 200 degree oven for two hours. In the summer, you can sun dry them, but it takes a bit longer.
And I looked, and behold a pale horse: and his name that sat on him was Death, and Hell followed with him. And power was given unto them over the fourth part of the earth, to kill with sword, and with hunger, and with death, and with the beasts of the earth.
