What would be a good product to use to clean natural river rock that has
been blackened from a fireplace? The smut seems to only be on the surface,
but it has been there a long time.

What would you recommend, and would you use a wire brush or something else ?

Thanks !!

Mix a solution of high-alkaline cleaner and one ounce of chlorine
bleach per gallon of warm water. . Wet the surface of the fireplace
well with the solution, but don't use so much that it runs. Dirty water
running down the face may cause hard-to-remove streaks. Then scrub with
a brush. You know it's working when the suds are black. This always
worked for us but time consuming. We use thick bristle brushes and
scotch guard pads.
