How should multi-part instruments be placed in the ultrasonic cleaner?

• A. In a single piece
• B. Disassembled
• C. With parts overlapping
• D. In a dedicated mesh bag

Answer: (B)

Multi-part instruments should be placed in the ultrasonic cleaner disassembled to ensure thorough cleaning. When instruments are fully disassembled, each component can be adequately exposed to the ultrasonic cleaning solution, allowing the cavitation bubbles produced by the ultrasonic waves to reach and clean all surfaces effectively, including intricate areas and crevices that may harbor bioburden and debris.

Placing instruments in a single piece or with parts overlapping can hinder the effectiveness of the cleaning process, as some areas may remain shielded and not receive the same level of agitation and cleaning action. While using a dedicated mesh bag can help contain small pieces, it still doesn't guarantee that each part will be cleaned as effectively as when they are disassembled. The primary goal of cleaning in an ultrasonic cleaner is to achieve the highest level of cleanliness, which is best accomplished when all components are separate and able to be thoroughly cleaned from all angles.
