Brazilian gray 9 marble is a beautiful and durable natural stone, but if it is not maintained and cleaned carefully, it can also be damaged by stains, scratches, cracks, etc., affecting its beauty and service life. Therefore, you need to maintain and clean the Brazilian Gray 9 marble regularly. The following are some common methods and precautions:

Cleaning: You should often remove dust and debris from the surface with a clean soft cloth or dust pusher to avoid abrasion of the marble. If there are stains or dirt, you can use a slightly damp cloth or sponge dipped in neutral or slightly alkaline detergent to wipe gently, then rinse with clean water, and dry with a dry cloth. You can also use an acid such as lemon juice or vinegar to remove some stubborn stains, but don't let them sit on the marble surface for too long, or it will corrode the marble 123.
Care: You should regularly wax or recrystallize your marble to increase its luster and wear resistance. Waxing is to coat a layer of waxy substance on the marble surface to close its pores and prevent stains from penetrating and water vapor from evaporating. Recrystallization is the use of chemical agents and mechanical friction to form a new layer of crystallization on the surface of marble to enhance its hardness and refractive index. You can choose the appropriate method according to your needs and budget, or ask a professional stone maintenance company to operate.
Precautions: You should avoid placing heavy, sharp or hot objects on the marble as it can cause dents, scratches or cracks. You should also avoid using cleaners or bleaches that contain strong corrosive ingredients such as acids, alkalis, chlorine, etc., so as not to damage the essence of the marble. If you accidentally splash these substances, you should wash them with clean water immediately and dry them with a dry cloth12.
