Research: Cleaning Efficiency and Practices

Cleaning has long been an integral part of metro operations, with a focus on manual and resource-intensive methods and following health and safety regulations. With the onset of the COVID-19 pandemic, cleanliness of public transport quickly took on greater prominence, gaining significant political and public interest and becoming a key area for testing and innovation.

Benchmarking of metro cleaning practices offers significant scope for efficiency. Even before COVID-19, cleaning made up almost 5% of an average metro’s operating costs, and as metros begin to recover from the pandemic and attempt to maintain enhanced cleaning standards under constrained budgets, it is essential that metros manage these costs and maximise effectiveness as far as possible.

Factors preventing more effective and efficient cleaning at metros

This study brought together information from 30 metros to explore cleaning trends leading up to the pandemic, including benchmarking on contracts, cleaning hours, and cleaning costs. The study also examined how practices, frequencies and staffing have changed as metros manage COVID-19. Lastly, the study included examples of new techniques, products and practices that have been implemented and found to improve cleanliness outcomes during COVID-19.
