The Role of Cleaning in Healthcare and Hospitals

Cleaning is the practice of removing unwanted substances such as dust, dirt, stains, or contaminants from an object, surface, or environment to improve its appearance, maintain hygiene, preserve functionality, or ensure safety. This economic perspective reveals that cleaning, while often invisible or taken for granted, has far-reaching impacts on prosperity and growth.

Within households, cleaning practices have changed over generations with the advent of modern appliances such as washing machines, dishwashers, and vacuum cleaners.

However, the increasing availability of professional cleaning services, automated devices, and specialized products has reshaped how families and individuals approach domestic chores.

Terminal Cleaning: Ensuring Sterile Environments

Engaging in tasks such as decluttering, organizing, or scrubbing can serve as a physical outlet for stress, helping to clear both the environment and the mind.
