Vinegar will help with the cleaning some what, but in effect it is really just a weak acid. For rocks I sterilize using standard bleach, if they are none porous. For wood I use oxygen bleach, Hydrogen Peroxide, because it breaks down much faster. If the source is reasonably safe and the piece has gone through a bone dry phase I don't necessarily sterilize the pieces.
Please note that I base this entirely on personal experience. I haven't had any diseases introduced or and leaching that caused issues with the fish, but perhaps it is luck on my part.
