Does professional training really affect cleaning quality across industries?-Forum-Culture Informatique

What became noticeable over time is how training changes the way tasks are handled from one visit to another. In a facility I was involved with, cleaning used to depend heavily on who was assigned that day, which led to uneven results. Later, I worked alongside a team delivering east london commercial cleaning, and their approach felt far more structured from the start. Instead of guessing what needed attention, they followed clear procedures and adjusted methods depending on whether it was a retail area, a kitchen space, or a more industrial section. It reduced the need for follow-ups and made the overall condition much more predictable. The consistency came not just from effort, but from knowing exactly how to handle each environment properly.
