Before disinfection, what must be done to the surface?

The appropriate step before disinfection is to ensure that the surface is cleaned. Cleaning involves removing dirt, debris, and organic matter from the surface, which is essential because disinfectants are more effective on clean surfaces. If contaminants are present, they can inhibit the action of the disinfectant, making it less effective in killing pathogens.

Cleaning typically involves the use of soap and water or a suitable cleaning agent to physically remove visible soils, oils, or residues. Once the surface is clean, it can then be properly disinfected to eliminate any remaining microorganisms, ensuring better hygiene and safety in a cosmetology setting.

In contrast, while other steps like sanitizing and clearing may seem relevant, they do not specifically address the requirement of removing visible contaminants in preparation for effective disinfection.
