Identifying and Treating Pollution on Surfaces

1. Identifying Pollution Types

The type of pollution can often be judged based on the color of the stain and its location. This helps determine the appropriate treatment method.

• Office Areas: Common pollutants include coffee, tea, ink, etc., as they align with office workers' habits.
• Construction Sites: Pollution may come from engine oil, rust, wood pigments, and other industrial materials.
• Restaurants: Stains often result from food, juice, soy sauce, and similar substances.
• Warehouse Floors: Contaminants like paint, oil, and moisture from wooden boxes should be considered.
• Toilets: Typically affected by sewage pollution.

2. Pigment Cleaning Method

Once the source of pollution is identified, cleaning becomes straightforward.

• The primary method is chemical decolorization, which breaks down the molecular structure of pollutants before removal.
• Avoid using strong acids, alkalis, or other destructive materials, especially on rainbow sandstone steps, as they can damage the structure and integrity of the stone. Professional cleaning agents are recommended for safe and effective cleaning.

Rusty Lesion Treatment Process

1. Determining Rust Spots

Rust spots on stone surfaces fall into two main categories:

1. External Rust Spots

   • Caused by welding ablation, steel cutting, scaffolding rain washing, iron stacking, etc.
   • They have distinct shapes, making them easy to identify based on their pollution source.

2. Self-Rust Spots

   • Occur due to the high iron content in the stone itself, leading to internal rust formation over time.

Proper identification of rust types ensures effective treatment and helps establish preventive measures to maintain stone surfaces.
