Any window sill made of strong marble can last not only years, but also decades, and at the same time, only the minimum will require care for it. Such products need to be wiped and washed when pollution appears on them, and nothing more. Behind cleanliness, you need to follow quite carefully, especially if the windowsill is white — spots of some kind are able to get into a stone. For example, it is precisely such properties that rust has. Fortunately, today there are many types of cleaning products that can get rid of such phenomena, and created specifically to care for marble. They will help to solve any problem with mud. Also, with prolonged operation, the stone surface can lose its perfect smoothness, but it will also be easy to solve such a problem — it will be enough to polish the stone, and the windowsill will again become excellent.
