What is the reasoning behind starting with the cleanest areas?

Starting with the cleanest areas is crucial in cleaning practices because it helps avoid spreading dirt and germs to previously cleaned areas. By beginning with the least contaminated surfaces, you minimize the risk of transferring pathogens and debris to spaces that have already been sanitized. This method not only maintains the cleanliness of those areas but also ensures the overall cleaning process is more effective, as once areas are cleaned, they should not be contaminated again by dirt or germs from less clean areas during the cleaning process.

Other choices do not align as directly with best cleaning practices. For instance, ensuring dirt is spread evenly is counterproductive, while allowing more time for cleaning the dirtiest areas isn’t as effective as maintaining cleanliness throughout the entire environment. Prioritizing areas with less foot traffic does not take into consideration the importance of hygiene and contamination control, which is the primary goal of a thorough cleaning protocol.
