Wipe the surface with a dampish cloth. For more thoroughly cleaning, use a cloth wrung in water with soap flakes (2-3 tablespoons of soak flakes for 1 liters of water). Regularly use of soap flakes will over time dull the surface.
Do not clean marble inventory with any kind of aggressively or sour cleaning liquids (vinegar, citric acid e.g.) If these liquids are spilled, it must be wiped of immediately.
Marble must be saturated with preservatives for absorbent material, so that grease and dirt do not enter the materials. Use petroleum or water with soap flakes and generate foam and apply the foam on the surface. Let it work for 5 minutes, without drying and wipe the surface with a clean and dampish cloth.
