What prefix should a cleaning agent have for effective hand scrubbing?

The correct choice, which is "Chlor-," refers to cleaning agents that contain chlorine compounds. Chlorine is well-known for its disinfecting properties and is widely used in various cleaning products to effectively kill bacteria, viruses, and other pathogens. The presence of chlorine enhances the cleaning agent's ability to sanitize surfaces, making it particularly effective for hand scrubbing in settings that require strict hygiene control, such as healthcare environments.

Using a cleaning agent with the "Chlor-" prefix indicates a strong capability to provide thorough disinfection. This characteristic is crucial when cleaning to prevent the spread of infections, making it a vital component in hand hygiene protocols.
