This is the correct way to polish marble. If you use strong chemicals or products not made for porous stone you will ruin the marble
How to:
- Crush up some white blackboard chalk until it is a fine powder. This will be used to shine the marble
- Dampen a microfiber cloth and dip into the chalk powder. Continue to dip into the powder and apply as needed
- Wipe the marble down in long, overlapping strokes. Make sure you wipe in straight strokes, working only with the grain. Do not work in circles
- Rinse the marble with cool water. Use a clean microfiber cloth to wipe off all traces of chalk
