What must be used to clean drips on a cup?

To effectively clean drips on a cup, a clean, sanitized towel is essential. Using a clean towel ensures that no contaminants are introduced to the surface of the cup, which is particularly important in environments where hygiene is critical, such as in food and beverage service. Sanitization helps eliminate any bacteria or pathogens that could be present, hence maintaining health standards.

A clean, sanitized towel is also designed to absorb moisture without leaving lint or residues, ensuring the cup remains pristine and ready for use. In contrast, other options, such as a paper towel or a dirty cloth, do not guarantee the same level of cleanliness. Paper towels are often used for single-use purposes and may not effectively sanitize surfaces, while using a dirty cloth could actually spread contaminants rather than eliminate them. Sponges might be effective for cleaning but can harbor bacteria if not properly sanitized, making them less suitable for this specific task. Thus, a clean, sanitized towel is the most appropriate choice for ensuring cups are free from drips and safe for consumption.
