Use a heat mat for hotplates and dishes, dust regularly with a mop, and use floor mats to protect marble tiles from unnecessary dirt. Do not use abrasive scouring sponges, wait until you remove dirt and stains, use heat mats on warm dishes and dishes, and dust regularly.
There are many natural stone cleaners that even clean dirty marble outdoors, but soap and scum can form quickly and contaminate the surface. These natural cleaners remove dirt and cake dirt without damaging the marble surfaces.
Other marble pieces that have come into contact with soapy water require regular cleaning, so they only need a few minutes a day for regular cleaning.
Fortunately, it is quite easy to remove soap scum and stains from marble, simply put a cup of ammonia on a gallon of water and wipe the surface clean. Be careful not to use too much ammonia, however, as it can cloud the marble surface and cause a build-up of soap and scum on the surfaces of your marble pieces. Be careful not to use it too often, as it can build up to your marbled surfaces and cause problems.
First, clean the entire worktop with acetone to remove the dirt and sealing from the marble. If you use marble countertops, a sealing will obscure the marks, but you can create tiny scratches that weaken the finish. Marble has a much higher surface area per square inch than other marble types, so use sparingly.
You can use baking powder on marble countertops, for example, but you have to be very careful. Once white vinegar and baking soda are out, you can make marble cleaners with other common things you have at home.
If your marble table has discoloration from food or other household items, you may need to treat it before you start polishing. I have never used white vinegar, baking soda, or any of the other common household cleaners to clean polished marble.
I may be here with product recommendations, but I advise you on maintenance issues, including "stain removal" above, so you don't need that. If there are commercially available marble stain removers, often referred to as envelopes, you can make your own by slowly mixing a tablespoon of ammonia with half a cup of hydrogen peroxide and adding just enough baking soda to produce a thick, creamy consistency. I use a strong cleaner that is also safe for marble, such as a high-quality, non-toxic bleach. Spray everything over and let rest for 5 - 10 minutes, then rinse with water and rinse again.
How to restore a tabletop from Georgia with white, pink, and brown veins to its original color with a little help from a high-quality bleach.
If your coat is as clean as you can get, you may find that the marble has lost some of its polish. Perhaps you can restore the shine by applying a polish specially designed for marble. If the surface is still rough after polishing, try wet sanding or even a little dry sanding - clean it before polishing and restoring the finish.
If the surface is very rough, start with some wet sanding or even some dry sanding before polishing and restoring the finish.
If the stain is very old and deep and the surface is in much worse condition than in the photos, you may need to hire a professional to sand and re-coat the marble, but I think that is unlikely in this case. It seems to be in a decent condition after all stains have been removed, except for some inevitable etchings that require the use of a marble polishing compound (recommended by the previous question). If there is a problem or if there are stains that are much older and deeper, you need the help of an expert in the restoration and cleaning of marble (for a complete step-by-step guide, see this link). The method itself is required to restore and clean marble, and you can do it in a few minutes or even a few hours.
Understand that this is not a typical or recommended way to obtain a marble countertop, but for most people, it is the best option.
If you want to maintain a good surface finish, sanded and polished, avoid acidic foods and drinks, and do not use hard acidic cleaners such as vinegar.
While granite and marble are natural materials, some items should not be used due to the risk of damage or scratches. Kitchen islands made of Carrara marble are less risky because they are the surfaces that are most stressed. Stopping marble etching on a kitchen countertop is simply impossible, but it can be stopped if the etching marks are still visible on the polished surface.
If you use a special marble or granite cleaner, you can clean it easily in hours or even days.
