What is the purpose of overlapping strokes when cleaning the PEC?

The purpose of overlapping strokes when cleaning the Primary Engineering Control (PEC) is to ensure that all areas are covered effectively. When using overlapping strokes, the cleaner can systematically pass over each section without missing spots. This method enhances the thoroughness of the cleaning process by providing consistent coverage across the entire surface area, which is crucial in maintaining a sterile environment.

By utilizing overlapping strokes, you can eliminate the risk of leaving residual contaminants in any area that might compromise the sterility of compounded preparations. This practice aligns with the guidelines and best practices for cleaning in sterile compounding, which emphasize the importance of achieving and maintaining aseptic conditions to protect patient safety and product integrity.
