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.
When you go home, tell them of us and say:
"For your tomorrow, we gave our today."
