Why did inspectors visit multiple stations?

Inspectors visit multiple stations to compare cleaning performance on different surfaces because this allows them to assess how effectively various cleaning methods and products work on distinct materials present in transit facilities. By observing and evaluating the cleanliness and condition of different surfaces across stations, inspectors can identify best practices, determine the most efficient cleaning techniques, and pinpoint any areas needing improvement.

This approach is critical in ensuring overall cleanliness and safety in the transit environment, leading to better maintenance strategies and enhanced service quality for passengers. Each station might have unique challenges or require different cleaning protocols based on the surfaces in use, thereby making cross-station comparisons a valuable tool for maintaining high standards in cleanliness.
