The effectiveness of hospital disinfectants in cleaning blood and body fluids is primarily associated with nonporous surfaces. Nonporous surfaces are those that do not allow fluids to penetrate them, making it easier to wipe away contaminants and ensuring that disinfectants can work effectively. These surfaces can be disinfected thoroughly because they do not absorb the fluids, allowing for complete cleaning and proper application of disinfectants to eliminate potential pathogens.

In contrast, porous surfaces, such as textiles and wood, can absorb fluids, which can make it more challenging to achieve complete disinfection. When blood or body fluids come into contact with porous materials, there is a risk that the pathogens may remain trapped within, even after disinfecting. Therefore, while hospital disinfectants are critical for infection control, their effectiveness is significantly diminished on porous surfaces, highlighting the importance of using them specifically on nonporous surfaces for optimal results in cleaning and disinfection.
