When cleaning stone, the following problems need to be noted:

1. Selection of Cleaning Products

• Avoid using strong acid and strong alkali cleaners
  Strong acid and strong alkali cleaners may have chemical reactions with the stone, damaging the stone surface, causing it to lose its luster or even present corrosion phenomena. Neutral cleaners suitable for the stone material should be selected.
  

• Use steel wool and other tools with caution
  Although steel wool can be used for stone cleaning in some cases, for some stones with a softer texture or specially treated surfaces, steel wool may cause scratches. Be cautious when using steel wool and determine whether it is applicable based on the specific situation of the stone.

2. Cleaning Methods

• Conduct a small area test first
  Before cleaning a large area of stone, conduct a test in an inconspicuous small area first, observe the impact of the cleaner and cleaning tools on the stone, and ensure that no damage is caused to the stone before conducting a comprehensive cleaning.

• Avoid excessive force when wiping
  Excessive force when wiping the stone surface may cause scratches or damage the structure of the stone. Control the force when using the cleaning tools and wipe gently.

• Pay attention to the cleaning sequence
  Generally, remove the dust and debris on the stone surface first, and then use the cleaner for cleaning. When cleaning, start from the edge of the stone to the center to avoid the cleaner remaining on the stone surface.

3. Daily Maintenance

• Clear stains promptly
  Once stains are found on the stone surface, they should be cleared as soon as possible to avoid the stains penetrating into the stone and increasing the difficulty of cleaning. Corresponding cleaning methods should be adopted for different types of stains.
  

• Conduct regular maintenance
  Regular maintenance can be carried out on the stone, such as waxing and applying protective agents, to enhance the wear resistance and stain resistance of the stone and prolong the service life of the stone.

4. Environmental Factors

• Avoid excessive contact with moisture
  Although the stone has a certain degree of water resistance, long-term contact with excessive moisture may cause the stone to change color, mold or be damaged. After cleaning, the moisture on the stone surface should be dried in time.
  

• Prevent high temperatures and direct sunlight
  High temperatures and direct sunlight may cause the stone to deform, crack or fade. Try to avoid long-term exposure of the stone to high temperatures and sunlight, and shading and other measures can be taken.
