The most common and practical method of instrument sterilization is moist heat, specifically through the use of autoclaving. This method involves using steam under pressure to achieve high temperatures that effectively kill bacteria, viruses, and spores present on surgical instruments. The process typically involves temperatures of around 121 degrees Celsius (250 degrees Fahrenheit) for a specific duration, which ensures thorough sterilization.

Moist heat sterilization is favored because it is reliable, efficient, and less damaging to instruments compared to some other methods. It can penetrate fabrics and reach all surfaces of the instruments, ensuring comprehensive sterilization. Additionally, it is generally faster than dry heat sterilization and does not require many of the hazardous materials associated with gas sterilization techniques.

While there are other methods of sterilization, such as dry heat, radiation, and gas sterilization, each has specific applications and limitations. Dry heat, for instance, requires longer times and higher temperatures, which can risk damaging certain instruments. Gas sterilization, while effective, often involves hazardous substances like ethylene oxide and requires careful handling and ventilation. Radiation sterilization, although effective in specific contexts, is less common in routine practice due to the need for specialized equipment and safety protocols.
