What is a crucial step in maintaining carpets after cleaning?

Applying a protector is a crucial step in maintaining carpets after cleaning because it enhances the carpet's durability and resistance to dirt, stains, and other substances that may disrupt its appearance and integrity. A protector creates a protective barrier on the fibers of the carpet, making it easier to clean up spills and preventing dirt from embedding deeply into the fibers. This proactive measure helps maintain the carpet’s cleanliness and extends its lifespan.

In contrast to this, allowing immediate foot traffic can lead to re-soiling and damage to freshly cleaned carpets. Using an air freshener may mask odors but doesn’t contribute to the carpet’s longevity or cleanliness. Although vacuuming twice a week can certainly aid in maintaining the cleanliness of carpets, it is not as effective as applying a protector immediately after professional cleaning in the context of long-term maintenance.
