Anyone had any experience in bringing their marble hearth back to its original glory.
I have been given a marble hearth but although the silicon around the edges (where they had laminate flooring) came of easy there is a black mark in the middle from coke/coal.
I myself have a Parkray 1/11 fire so it will come into contact with coke dust again but would like to know how to get clean in the first place.
Cheers
