And if you use anything too stong, a “marble polish” wonÂ’t do anything for it — nor will it remove ink. Add a little hydrogen peroxide, stirring and adding more until the mixture has a paste-like consistency that does not run. Clean the marble with hot water and several drops of mild soap if there is other residue to clean. If using a poultice follow the instructions given and instead of using hydrogen peroxide, and oxygenating bleach, use a solvent. Pour a small amount of distilled water over the stain to saturate the area, which helps lift the ink away. Scoop the poultice paste out over the stain or stains, spreading it into a 1/4-inch thick layer.
