Using an autoclave or a disinfectant solution is the proper method for sterilizing hair care tools because it effectively eliminates all microorganisms, including bacteria, viruses, and fungi. Autoclaves use high-pressure steam to create a sterile environment, ensuring that any tool that enters is free from pathogens. Similarly, disinfectant solutions are formulated to kill or inhibit the growth of these harmful organisms and are essential when sanitizing tools that come into direct contact with the skin or hair.

Soaking tools in hot water, wiping with a dry cloth, or simply storing them in a drawer do not provide sufficient sterilization. Hot water may not reach the necessary temperatures or hold long enough to kill all microbes. Wiping with a dry cloth does not remove contaminants effectively, nor does it sanitize the tools. Storing tools in a drawer does not contribute to their cleanliness or safety, as it does not involve any cleaning or disinfecting method. Therefore, the use of an autoclave or disinfectant solution is the only approach that ensures tools are properly sterilized and safe for client use.
