Which type of porous material is likely to be damaged by water-based cleaning processes?

Certain porous materials are more susceptible to damage from water-based cleaning processes due to their physical properties and the nature of their composition. Type 2 porous materials are typically those that are more absorbent, such as certain kinds of fabrics, carpets, or other soft materials that can readily absorb moisture. When exposed to water-based cleaners, these materials may swell, lose their structural integrity, develop mold or mildew if not dried properly, or even undergo changes in color or texture.

In contrast, Type 1 porous materials tend to be more resistant to water-based cleaning processes. These are generally more durable or less absorbent, making them less likely to sustain significant damage. Therefore, when considering the vulnerabilities of different types of porous materials, Type 2 is identified as the more likely category to be affected adversely by water-based cleaning methods. This understanding is crucial for professionals in the trauma and crime scene cleaning field as it directly influences their choice of cleaning techniques and materials depending on the surfaces they are treating.
