The first step in the endoscope reprocessing cycle is pre-cleaning. This crucial initial step involves removing any organic material, such as blood and body fluids, from the endoscope immediately after use. Effective pre-cleaning is vital because it ensures that soil does not harden or dry onto the instrument, which can make subsequent cleaning and disinfection more difficult and less effective.

Pre-cleaning typically includes rinsing the endoscope with water to help eliminate debris and using appropriate enzymatic solutions to break down proteins and other contaminants. This step sets the stage for subsequent processes, such as cleaning, disinfection, and sterilization, by ensuring that the endoscope is in the best condition for those stages. If pre-cleaning is neglected or performed poorly, it can compromise the effectiveness of the entire reprocessing cycle, potentially leading to patient safety risks and equipment damage. Therefore, establishing pre-cleaning as the foundational step is essential for ensuring the safety and efficacy of endoscope reprocessing.
