What is the recommended procedure for cleaning Low Observable surfaces?

The recommended procedure for cleaning Low Observable surfaces emphasizes the importance of using approved cleaning agents and soft materials. This is crucial because Low Observable (LO) technology is sensitive and designed to minimize radar signature. Therefore, harsh methods, such as abrasive cleaning tools or high-pressure washing, can damage the delicate surfaces or coatings that contribute to the aircraft's stealth capabilities.

Approved cleaning agents are formulated specifically for use with these materials, ensuring that they effectively clean without compromising the structural integrity or the radar absorbent properties. Soft materials, like microfiber cloths, are essential to avoid scratching or damaging the surface. This careful approach helps maintain the effectiveness of Low Observable features, prolonging the lifespan of the aircraft's treatment against radar detection, while ensuring the surfaces remain clean and functional.

In contrast, using abrasive tools, water and detergents, or high-pressure methods may lead to unintended damage or insufficient cleaning, which could impair the aircraft's performance and maintenance requirements.
