A friend uses hydroton. He pulls out the big roots, then spreads it out in the sun or under a heat lamp to get very dry, rubs it vigorously on hardware screen in a frame of 2x4's until the organic stuff separates, falls apart & through the screen. Then rinse & re-use. He hasn't had any of the kinds of problems where he feels he needs to sanitize it.
