Altman marble is a high-grade natural marble, which has the characteristics of hard texture, high gloss, corrosion resistance and easy cleaning. However, if you do not pay attention to maintenance and cleaning, it will also be damaged by stains, scratches, cracks, etc., which will affect its appearance and service life. Therefore, you need to maintain and clean Altman marble regularly. Here are some common methods and precautions:

- **Cleaning**: You should frequently remove dust and debris from the surface with a clean soft cloth or dust pusher to avoid abrasive 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 marble¹²³.
- **Maintenance**: You should regularly wax or recrystallize your marble to increase its shine 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 marble surface, enhancing its hardness and refractive index¹². 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 may 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 spill any of these substances, you should immediately wash them off with clean water and dry with a dry cloth¹².
