Cleaning rocks...

How do you sufficiently clean rocks that are far too large to boil in a pot? Aside from scrubbing that is.

Toss it in a rubbermaid tote with a bleach mix?

First, you shouldn't boil rocks. They have a tendency of "exploding" at high temps. Drop it in a tub of 50/50 bleach and water for a few hours.
