Substances that may contain solvents, corrosives, or any number of chemicals to clean an aircraft.

• A. Degreasers and Strippers
• B. MSDS
• C. Cleaners
• D. Coatings

Answer: (C)

The main idea here is recognizing the broad category of products used to clean aircraft surfaces. Substances used to clean can include solvents, caustics, and various other chemicals to remove dirt, grease, and coatings. The general term that covers all of these cleaning agents is cleaners. Degreasers and strippers are specific types of cleaners chosen for heavy-duty jobs like removing grease or coating layers, but they’re still within the overall category of cleaners. An MSDS (Safety Data Sheet) isn’t a cleaning product itself; it’s the document that explains hazards and handling for those substances. Coatings are finishes applied to the aircraft and aren’t used for cleaning. So cleaners is the correct, broad category for substances that may contain solvents, corrosives, or other chemicals used to clean an aircraft.
