Manual cleaning needs to be performed as soon as possible upon entering the decontamination area to prevent the formation of biofilm. Biofilm is a slimy film of bacteria that can form on surfaces when they are not cleaned promptly. If biofilm is allowed to develop, it can protect bacteria from disinfection and sterilization processes, leading to potential contamination of medical devices. Therefore, performing manual cleaning promptly is essential to prevent the formation of biofilm and ensure the effectiveness of subsequent decontamination processes.

Option A is incorrect because manual cleaning does not directly expedite the sterilization process. It is an essential step in the decontamination process but does not affect the speed of sterilization. Option B is incorrect because while meeting regulatory requirements is important, the primary reason for immediate manual cleaning is related to preventing biofilm formation. Option D is incorrect because manual cleaning is not primarily about achieving a higher level of disinfection, but rather about preventing biofilm buildup.
