What should be avoided when cleaning LO treatment areas?

When cleaning Low Observable (LO) treatment areas, it is essential to avoid using harsh scrubbers or abrasive materials because these can damage the delicate surfaces and coatings that are critical for maintaining low observability. The LO treatments are specifically designed to minimize radar (and other forms of detection) signature, and using abrasive or harsh cleaning tools can compromise these treatments, leading to degradation or removal of the protective layers.

In the context of cleaning techniques, soft rags and non-abrasive cleaners, gentle solvents, and mild soap with water are considered safe options. These materials are less likely to cause physical harm or chemical reactions that could compromise the LO surfaces. Therefore, the emphasis on avoiding aggressive cleaning tools and materials is crucial for preserving the integrity and effectiveness of the low observable technologies applied to the aircraft.
