The recommended type of detergent for cleaning endoscopes is non-foaming and free rinsing. This is because non-foaming detergents minimize the risk of residues that could inhibit the effectiveness of subsequent disinfection processes. Foaming agents can create bubbles that may be difficult to rinse away completely, potentially leading to the accumulation of soap residues within the lumens of delicate endoscopic instruments. A detergent that is free rinsing ensures that it can be easily washed away during the cleaning cycle, reducing the likelihood of any detergent residue remaining on the endoscope. In the context of medical instruments, it’s critical to prevent any substances that could interfere with disinfection or leave harmful residues.

Other types of detergents, such as those that are highly foaming, strongly scented, or thick and gel-like, may not effectively clean endoscopes and pose risks of residue or ineffective cleaning. Thus, using a non-foaming and free rinsing detergent is crucial in maintaining the safety and functionality of endoscopic equipment.
