Crema Marfil is a very delicate and elegant marble not ideal for kitchen use due to its calcareous nature, or chalky characteristic. It can easily be damaged by acids, causing unwanted and probably permanent and irreversible etchings. It also is highly porous, so staining is very common.
If you find that the marble surface you cleaned a few days ago has discolored, you could try this to get back the shine. First, check to see whether the discoloration is rough and dull. Then check all the grout and caulk lines to check for any water seepage. The discoloration might be a form of efflorescence.
If you find that your marble floor had small white patches, it could be the result of marble stunning. Marble stunning occurs when little explosions occur in the crystals of the marble, because of concentrated pressure applied in that area. Women walking on marble wearing heels are a common cause of stunning.
Marble is a natural rock generally used in fine building work, floorings, home décor items and for counter tops. Over the time it gets worn down and loses its shine. To maintain it and keep looking best, it is important to take the proper care of it. If there is no care and normal maintenance, it can be dulled and stained. Polishing done by a professional contractor such as Colonial Floor Care, can help to regain luster and brightness of the marble. However marble requires high level of polish but when it is polished, it shimmers and shines like smooth glass.
