What is the recommended duration for hand scrubbing?

The recommended duration for hand scrubbing, particularly in a surgical or clinical setting where there is a need for thorough decontamination, is typically 3 to 7 minutes. This time frame allows for a significant reduction of pathogens on the skin's surface and is based on guidelines that help ensure effective removal of dirt and microorganisms.

Scrubbing for at least 3 minutes ensures that the friction and contact time are sufficient to lift and remove contaminants from the skin. Extending the duration to about 7 minutes can provide even better results, especially in preparation for sterile procedures. This duration also helps to ensure that the entire surface of the hands and forearms, including difficult-to-reach areas, are adequately cleaned. Thus, the choice falls within recognized best practices for infection control, particularly in healthcare environments.
