We use a product called Aquamix which we bought at Lowes. It is for
deep cleaning of stone or porous(sp) surfaces. It's a bit more user
friendly than the industrial types - ie: product used in a steam
cleaner for engine cleaning. I guess the blackened stone is from smoke
which is acidic and an alkaline cleaner lifts it. all i know that it
took off 60 years of sute off our fireplace brick.
