What are common light-duty cleaning agents used in aircraft cleaning?

The common light-duty cleaning agents used in aircraft cleaning are soap or detergents and water. This combination is effective for removing dirt, grease, and general grime from aircraft surfaces without causing damage. Soap and detergents are formulated to break down oils and contaminants, making them easy to wash away when mixed with water.

In aviation maintenance, the choice of cleaning agents is critical because aircraft surfaces have specific requirements to prevent corrosion, maintain structural integrity, and ensure safety. Unlike harsher chemicals such as bleach or vinegar, which can damage sensitive materials, or solvents and acids that may corrode or degrade surfaces, soap and water provide a gentle yet effective means of keeping aircraft clean. Additionally, using engine degreasers is typically reserved for specific maintenance tasks rather than general cleaning, which makes soap and water the preferred choice for routine cleaning applications.
