Just as ASVInteriors said, different kinds of stains require certain techniques and substances to clean them. Although you can find a variety of recipes on the web for cleaning marble, it helps to have a pretty good idea of how your particular stone will respond and what kind of stain you have. We have created resources for helping customers understand what is involved in cleaning specific marbles on our site. Your question is for "Italian Marble" and since Carrara is one of the most common, this link might be helpful to others looking for the same information: https://www.lustroitaliano.com/about-carrara-marble-s/1992.htm#cleaning-carrara-marble

I think the marble naysayers have jumped on the bandwagon without really living with the stone. I have statuary in my bathrooms and love it. Most stains can be removed with a simple baking soda and water poultice. Acid etching is harder to deal with since it removes the polished surface, but its part of having a living stone in your home. If it becomes too bad, you can have it repolished. With a darker stone, you won't have as many issues as a white marble. In order to really know if you can live with it, I suggest you get a small sample of the stone and do some tests. Here is an example. http://www.dohiy.com/2013/04/21/marble-countertops-the-post-acid-test/ Please note that she used bleach and oxyclean to clean the stone after her test. Stay away from both since they can etch the stone just as much as an acidic food. Instead, clean with a ph neutral cleaner like isopropyl alcohol (rubbing alcohol), and for heavy stains, the baking soda poultice mentioned above. You have to remember that marble has been used for centuries as flooring, table tops, countertops, etc. throughout the world and most of these installations are still here and aren't stained and etched to the point that it has been ripped out and replaced. Just think about all of he luxury hotels in Europe and how many times they have been exposed to Hangover type guests without any damage.

first of all, Thank you guys for those valuable inputs. yes, as far as cleaning goes, its just been finished installing and I have asked them to clean them up. And also, I observed that the frosting on the glass didn't look that good, so I am going for the filming on certain portions of the doors n windows. - Is there a particular quality of films that I may choose for this ? - Yes, lighting is definitely the criteria I had in mind which can bring up the finish to this. And i am worried about this , as I did not go for False Roofing, bcos the ceiling is already at a low height. I should really refine my ideas on the lighting part. - the stairs are floored with white Marble stone..My mom loves it and the matting on it might hinder its beauty, but yes I will surely consider that as well. Thank you again.

Ashish, The workmanship seems to be an issue with your stone cladding wall. Interlock joints are visible and dirty. This needs to be thoroughly cleaned and grey cement will need color touch ups. Some people go for a lacquer polish to enhance the look of the stones. However, it is equally repulsive for some people who like natural finish. Get a sample stone done first and then decide for the entire wall. It appears to be sandstone, hence it is better if it is coated with lacquer. Thanks, Nitin CORNERSTONE DESIGNS, Bangalore
