Which step is the first in the processing of instruments?

Cleaning is the first step in the processing of instruments because it is essential to remove organic and inorganic debris from the instruments before any further processing. Proper cleaning ensures that sterilization and disinfection are effective. If instruments are not thoroughly cleaned, residual contaminants can shield microorganisms from the action of disinfectants or sterilants, rendering these processes ineffective.

During the cleaning phase, various methods such as manual scrubbing, ultrasonic cleaning, or using automated washers can be employed to ensure that all surfaces of the instruments are free from contamination. This step is critical for maintaining infection control standards, as it lays the groundwork for subsequent processes like disinfection and sterilization, which cannot be successful if instruments are not properly cleaned first.
