Buff the scratched area with the paper towels using moderate force to buff out any remaining visible scratches.
Buff out minor scratches in your granite or marble top with dry number 0000 steel wool.
Conceal a minor scratch with a color-matched paint marker, as recommended by the Natural Stone Interiors website. Apply the color to the scratch and remove the excess with denatured alcohol on a cleaning rag.
