What does "clean" refer to in a cosmetology context?

In the context of cosmetology, "clean" specifically refers to being free from all soil and dirt. This means that work surfaces, tools, and equipment must be visibly free of dust, debris, and any organic matter. Cleanliness is the foundational step for maintaining hygiene standards in any cosmetology setting, as it prevents the growth and spread of bacteria and other pathogens.

While sanitation and disinfection are crucial elements of maintaining a healthy environment, they go a step further than just being clean. Sanitation typically involves reducing the number of microorganisms to a safe level, while disinfection involves using specific chemical agents to kill pathogens. Therefore, the term "clean" is fundamental and refers specifically to the absence of visible contaminants rather than the processes involved in further germ reduction or chemical treatment.
