What is the primary purpose of placing instruments in a holding solution?

The primary purpose of placing instruments in a holding solution is to prevent the drying of blood and organic matter. When instruments are used in dental or medical procedures, they often become contaminated with blood, saliva, and other organic materials. If these substances are allowed to dry on the instruments, they become much more difficult to remove and can compromise the effectiveness of subsequent cleaning and sterilization processes.

By immersing the instruments in a holding solution, you maintain their cleanliness and make it easier to clean them thoroughly later on. This practice is crucial in infection control because it helps ensure that all contaminants are effectively removed before the sterilization process begins, thus minimizing the risk of infection and ensuring that the instruments are safe for future use.
