Sanitation, Sterilization, and Safety Practices
Clean, disinfect, sterilize
Cleaning removes visible debris with soap or detergent and water. Disinfection destroys most pathogenic organisms on tools and surfaces; sterilization destroys all microbial life and is generally reserved for surgical instruments, not routine hair tools. Michigan cosmetology sanitation rules require tools to be cleaned and then disinfected before each client with an EPA-registered hospital-grade disinfectant used exactly per label contact time. Immersion is required when the label directs it.
Single-use and linens
Porous items that cannot be disinfected-emery boards, wooden sticks, cotton swabs, neck strips-are single-use. Towels and capes must be clean for each client and soiled linens kept in a closed container. Shampoo bowls, chairs, and surfaces are cleaned and disinfected between clients. Hands are washed before and after service; gloves are used for blood or body-fluid contact.
Worked example
A metal comb falls on the floor. The culturist picks it up with a clean paper towel, removes visible debris, washes it with detergent and water, dries it, then immerses it in the labeled disinfectant for the full contact time before reuse. She does not simply wipe it with a towel or spray it and use it immediately. Reasoning: cleaning must precede disinfection, and contact time is part of the label directions.
Traps
Topping off disinfectant, skipping contact time, using a UV cabinet instead of a chemical disinfectant, storing clean and dirty tools together, and reusing towels are common failures. Change solutions when cloudy or at the required interval.
