Sterilization means destroying all forms of microbial life, including spores, and the method that reliably does this for barber instruments is autoclaving. An autoclave uses saturated steam under pressure to penetrate instruments and reach internal surfaces, giving consistent, validated sterilization for tools that contact skin and mucous membranes.

Boiling water for five minutes is a strong disinfection method but does not guarantee sterility, and spores or heat-resistant forms can survive. Wiping with alcohol only disinfects surfaces and does not penetrate all areas or kill spores, so it’s not sterilization. Air drying without heat leaves any microbes intact. So autoclaving is the appropriate method.
