I have a stone fireplace. What is the best product and method of
cleaning soot off the front face of the fireplace? This is a natural

stone, just remove the soot !!

Soot is carbon.

Carbon is soluble (ever so slightly) in only one substance: molten iron.

This means, in your case, that soot removal must be mechanical; there is no
chemical process available.
