Builders use marble in many parts of some homes from the floors to the bathroom sinks. Marble is a common material for tabletops as well. Over time, marble begins to look dull, but rubbing the natural stone with mild abrasives helps to restore the original shine of your marble.
Polish a Lightly Dulled Surface
Make a mixture of 3 tablespoon of baking soda and 1 quart of water in a spray bottle.
Spray some of the baking-soda mixture onto your marble surface. Wipe with a chamois cloth. Leave the surface of the marble a little damp and allow it to air dry.
Crush up a stick of chalk into a small bowl.
Dampen a clean chamois cloth with water. Dip the damp chamois into the chalk and rub it all over the surface of the marble.
Rinse off the marble with a fresh damp chamois. Dry the marble surface thoroughly with another chamois to reveal a high shine.
Polish a Scratched Surface
Load your hand sander with the 600-grit sandpaper. Go over the entire surface of the marble.
Wipe off the marble with a damp chamois to remove any dust.
Put the next highest grit sandpaper on the sander and sand again.
Keep sanding with the next highest grit, wiping the marble after each time until the surface of the marble appears shiny.
Buff the marble with a chamois cloth to enhance the shine of the stone.
