Stone products boast a simple and elegant color, making them a popular choice for architectural decoration. They bring a unique style to the overall environment, showcasing a refined aesthetic beauty. In Shandong, the cleaning of bollards varies—some involve superficial surface treatments, while others entail multi-level cleaning. For stone with microstructures already damaged, if the surface has lost its luster and shows signs of chipping and peeling, we must conduct a deep cleaning immediately.

Thorough cleaning is essential, as it involves different cleaning methods tailored to the various causes and targets of stone diseases. The cleaning of stains deeply embedded in the micropores of decorative stone is referred to as "deep cleaning" for stone. Generally, deep cleaning of stone should at least include the following three steps:

1. The cleanser penetrates the stone's micro-pores through a渗透 process.

2. The cleaner interacts with dirt molecules in the microscopic pores of the stone through either physical or chemical action.

3. Remove residuals after cleaning by extracting or diluting.

Here, Steps 1 and 3 are the basic operations necessary to complete the deep cleaning of Shandong stop ball, while Step 2 requires the careful design and experimentation of a cleaning agent that can interact with dirt molecules, depending on the nature of the dirt, the material of the stone, and the convenience of the process. Chemical methods have a unique effect here.
