Which term is used for cleaners designed to dissolve grease on a molecular level?

• A. Tetrodotoxin
• B. Staphylococcus Aureus
• C. Symptomatic Carrier
• D. Solvent Cleaners/Degreasers

Answer: (D)

Grease removal relies on solvents that can dissolve nonpolar substances. Solvent cleaners/degreasers are formulated with liquids that solvate greasy films, breaking the interactions holding the grease to the surface and pulling the hydrocarbon molecules into solution. This means the grease dissolves at the molecular level, making it easy to rinse or wipe away. It’s different from water-based cleaners, which mostly rely on surfactants to emulsify oils so they can be washed away in water rather than truly dissolving the grease. The other terms don’t fit because they refer to things unrelated to cleaning chemistry. Tetrodotoxin is a toxin, Staphylococcus aureus is a bacterium, and a symptomatic carrier is a disease-epidemiology concept.
