Mix your cleaning solution: Fill the gallon bucket about three-quarters of the way with warm water. Then add about half a cap full of bleach. This cleaning solution will lift dirt and lighten stains without harming your marble.
Wipe down the marble with the cleaning solution: You can just dip a cleaning rag in the solution, then wring it out and wipe down the benchtop. Rinse often to make sure that you are not smearing old dirt around on the benchtop.
Treat stains with baking soda and salt: Once you have cleaned off the benchtop, you may notice some stained areas on the surface. Apply a paste of baking soda and salt to these stains. You can mix about a tablespoon of each in your hand using a damp toothbrush. It will form a chalky paste. Use the toothbrush to apply the paste to the stain, then let it sit for about 15 minutes. Scrub the paste away with the toothbrush.
Wipe down the benchtop again with the bleach solution. Once all the stains are gone, you can reapply the bleach solution to make sure there are no streaks from your stain treatment.
Polish your benchtop with turpentine: Dip a clean cloth in the turpentine and polish the benchtop to get a brighter, shinier surface. Apply only a thin coat, and rub it thoroughly so that no turpentine is just sitting on the top of the marble.
