The first step in any sanitation process is to clean surfaces with soap and water. This initial cleaning is crucial because it removes dirt, debris, and microorganisms from surfaces, which prepares them for the subsequent disinfection process. Simply disinfecting without first cleaning may not be effective, as disinfectants work best on surfaces that are free from soil and organic material.

Cleaning with soap and water not only physically removes contaminants but also helps to lower the number of pathogens present, making the disinfection more effective. This foundational step is essential in both personal hygiene practices, such as washing hands, and in maintaining a safe and sanitary environment in a salon or spa setting. Therefore, prioritizing cleaning with soap and water sets the stage for effective sanitation overall.
