What is Marble?
Marble, from Greek: marmaros (shining stone) > Latin: marmor > Italian: marmol was the designation given to ANY stone that would take a polish. Today it is more strictly defined as a metamorphosed limestone composed mainly of calcite or dolomite. Because the main mineral is calcite and dolomite they do not get along well with acids. You may remember from chemistry class that acids and bases are locked in an eternal struggle to neutralize each other. The net effect for you marble surface is not catastrophic. At worst, typical household acids (citrus, vinegar, some cleaners) will not do permanent damage to your marble top. If your marble is polished, contact with acid will make that area look dull, or ‘honed’ as we call it in the industry. These areas can be re polished and brought back to their original glory. Many design professionals are specifying honed marble surfaces thus alleviating the need for future restoration.

Care & Maintenance
In the vast majority of situations marble and limestone can be cleaned with warm water and a mild detergent such as dishwashing liquid. Harsh cleaners must be avoided to avoid etching and in the case of an abrasive cleaner, scratching. Never use a cleaner that contains lemon juice or vinegar, these will etch the surface of your stone.
Spills
Blot the spill with a paper towel immediately. Don’t wipe the area, it will spread the spill. Flush the area with water and mild soap and rinse several times. Dry the area thoroughly with a soft cloth. Repeat as necessary.
Stain Removal – Marble & Limestone
There is a very effective home remedy for removing stains in marble and limestone. Mix baking soda with water to about the consistency of peanut butter, spread the mixture over the surface of the stain and cover with plastic wrap. Let the mixture sit for 24 hours, remove the plastic wrap and wipe up the baking soda mixture. Allow the area to dry thoroughly. Once dry the stain will be removed or greatly reduced. If needed repeat the process for a second time. If the stain still persists it may be necessary to call a professional stone restorer.
