Which items were not utilized in the washing of ceilings?

The correct answer identifies rags as the items not utilized in the washing of ceilings. In ceiling cleaning, items like sponges and scrapers are commonly used due to their effectiveness in removing dirt and grime from flat surfaces. Sponges provide a gentle yet effective way to clean, as they can conform to the ceiling's surface while holding cleaning agents. Scrapers may be used to tackle tough stains or build-up, ensuring a thorough clean.

Cloths are also a standard cleaning tool, particularly for final touches or to wipe away cleaning residues. They tend to be less absorbent compared to sponges but are very effective in drying surfaces or polishing.

Rags, while useful in various cleaning tasks, are often not the preferred tool for ceiling washing. They may not be effective in reaching high surfaces or providing the necessary cleaning power for larger areas. Additionally, rags can leave lint or fibers that might be undesirable when cleaning ceilings. Therefore, the choice of not using rags in washing ceilings makes practical sense for achieving a clean and polished finish.
