What is the essential first step to ensure success in the disinfection process on fomites?

The essential first step in the disinfection process on fomites is physical scrubbing with detergent and rinsing with water. This step is critical because it removes dirt, organic matter, and microorganisms from the surface. If a surface is not cleaned properly, contaminants can hinder the effectiveness of the chemical disinfectants that are applied afterward. Physical scrubbing helps to break up and lift away debris, which can harbor pathogens and protect them from the action of the disinfectant.

After scrubbing, the rinse with water helps to wash away residual dirt and detergent, leaving a clean surface that allows the disinfectant to work effectively. This cleaning process is foundational to achieving a truly disinfected environment, as disinfectants are not as effective when they encounter dirt or organic material. By prioritizing this cleaning phase, the subsequent use of chemical disinfectants can be more effective, leading to better infection control outcomes.
