What should be used for soft cleaning of Low Observable surfaces?

Using approved cleaning agents and lint-free cloths for the soft cleaning of Low Observable surfaces is essential because it ensures that the cleaning process does not damage the delicate coatings that are integral to the aircraft's stealth capabilities. Approved cleaning agents are formulated to be effective while being gentle enough to preserve the integrity of Low Observable technologies, which are designed to reduce radar reflectivity. Lint-free cloths help to minimize the risk of leaving behind particles that could compromise the surface finish or functionality.

In contrast, using rough scrub brushes can lead to scratching and damaging the Low Observable coatings, potentially negating their effectiveness. High-pressure rinsing can also be harmful as it may strip away or disrupt the coatings, creating vulnerabilities in the material. Standard detergents and sponges lack the specific formulations required to maintain Low Observable surfaces and could likewise cause unwanted wear or damage. Therefore, the use of approved agents and tools is crucial for effective maintenance without compromising the stealth features of the aircraft.
