What is a characteristic of degreasers used in sanitation?

Degreasers are specialized cleaning agents designed to remove grease, oil, and other tough contaminants from surfaces. The characteristic of being highly alkaline is crucial because alkaline substances are effective at breaking down fats and oils. The high pH level helps to emulsify and lift grease away from surfaces, making it easier to clean effectively.

In contrast, other choices do not align with the properties of degreasers. Neutral pH cleaners do not possess the necessary chemical properties to effectively tackle tough grease. The suggestion that degreasers are only for industrial use is misleading, as they can be used in various settings, including kitchens and households. Lastly, many degreasers do contain solvents which assist in their cleaning ability, contrary to the claim that they contain no solvents. Understanding these properties helps identify degreasers as powerful tools in sanitation practices.
