When does scraping take place in the cleaning process?

Scraping occurs at the beginning of the cleaning process, specifically before scrubbing. This step is essential for effectively removing larger debris, buildup, or residues that can be present on the surfaces to be cleaned. By scraping first, operators can prepare the area for more thorough cleaning by scrubbing, as any significant particles or substances will be lifted off before applying scrubbing techniques. This ensures that scrubbing is more effective and that cleaning agents can work on a cleaner surface, resulting in a more efficient and successful cleaning outcome.

In contrast, rinsing typically comes after scrubbing or any abrasive cleaning steps, which is not the sequence for scraping.
