Laser cleaning can be used not only to remove organic contaminants but also to clean inorganic compounds. The principle of laser cleaning involves utilizing the high energy density of the laser beam to cause evaporation or peeling of substances such as dirt or coatings, thereby cleaning the surface. This process does not rely on the chemical properties of the substances, allowing laser cleaning to be applied to a wide range of materials, including both organic and inorganic substances.

For example, in the field of cultural relic restoration, laser cleaning equipment can be used to remove oxides and other contaminants from metal surfaces, as well as dirt and mold from stone surfaces. In the industrial sector, laser cleaning equipment can be employed to clean oxides, oil stains, and welding slag from metal surfaces, as well as coatings and dirt from glass and ceramic surfaces.

It is important to note that different types of laser cleaning equipment may have varying applicability to different materials and contaminants. Operators must select the appropriate laser cleaning equipment and parameters based on specific conditions to ensure both cleaning effectiveness and safety.

According to incomplete statistics, laser cleaning equipment has already been applied in many fields, including:

1. Industrial Manufacturing: Laser cleaning equipment can be used to remove oxides, oil stains, and welding slag from metal surfaces, improving production efficiency and product quality.

2. Cultural Relic Restoration: Laser cleaning equipment can be used to clean oxides and other contaminants from metal surfaces, as well as dirt and mold from stone surfaces.

3. Art Restoration: Laser cleaning equipment can be used to remove dirt and aging substances from the surfaces of paintings and sculptures, restoring their original colors and textures.

4. Healthcare: Laser cleaning equipment can be used to clean medical devices and surgical instruments, improving healthcare quality.

5. Environmental Protection: Laser cleaning equipment can be used to remove dirt and coatings from building surfaces, reducing air and water pollution.
