What is a disadvantage of dry heat sterilization?

A disadvantage of dry heat sterilization is that it involves a long cycle, can discolor fabrics, and is not suitable for heat-sensitive items. This method relies on high temperatures over extended periods to achieve sterilization, which can turn certain materials, particularly textiles and plastic, discolored or damaged. Moreover, because of the prolonged exposure to high heat, this technique cannot be used for items that might be adversely affected by such temperatures, like those made of rubber or certain plastics.

In contrast, the other options highlight aspects that don't accurately represent the disadvantages of dry heat sterilization. Some methods might indeed have shorter cycles or be safe for temperature-sensitive instruments; dry heat does not fulfill these criteria. Additionally, dry heat sterilization is effective for a wide range of surgical instruments, which contradicts the limitations outlined in the context of heat sensitivity, while it does not require water or moisture, distinguishing it from steam sterilization methods that rely on moisture.
