Which chemical is utilized for cleaning the menu boards?

The correct answer is multi-purpose spray. This cleaning solution is designed to effectively remove various types of stains and dirt from different surfaces, including menu boards. Multi-purpose sprays are formulated to accommodate a variety of materials, making them suitable for the diverse surfaces found in a restaurant setting.

Using a dedicated multi-purpose cleaner ensures that the menu boards not only are clean from grease or fingerprints but also maintain the integrity of the board's surface without causing damage or leaving streaks. This is particularly important in maintaining a professional appearance that aligns with Taco Bell's standards.

While glass cleaner, all-purpose cleaner, and disinfectant are all useful cleaning products in various contexts, they may not be specifically formulated for the requirements of a menu board. Glass cleaner is typically optimized for glass surfaces, which may not be applicable for all menu board materials. All-purpose cleaners, while versatile, might not provide the specialized care required for certain finishes. Disinfectants are important for sanitization, but if the focus is on general cleaning and presentation, a multi-purpose spray would be the best fit for this specific task.
