What is a common step in both cleaning and disinfecting?

The correct answer highlights the fundamental process that connects both cleaning and disinfecting, which is the application of a solution to the surfaces being treated. Cleaning involves the removal of dirt, dust, and organic materials, while disinfecting specifically targets pathogens to eliminate them from surfaces. In both cases, applying a liquid solution—whether it's a cleaning agent or a disinfectant—is essential for effectively carrying out these processes.

Wearing gloves is a protective measure commonly practiced to safeguard the individual performing these procedures, but it is not a direct step involved in either cleaning or disinfecting. Drying the surfaces immediately is not a standard step, as it's more about allowing the cleaning or disinfecting agent to work effectively. Lastly, using hot water exclusively is not a universally applied method; while it may enhance cleaning in some scenarios, it's not necessary for disinfecting and can vary based on the products being used.
