Environmental dust contamination forms when airborne particles settle on surfaces in natural regional patterns, especially in humid areas of Taiwan. This contamination, it accumulates unevenly and adheres tightly to materials like metals or optics. Formation reveals unique layering, thus creates irregular deposits that resist uniform exposure. Laser cleaning applies pulses, but dust scatters energy and reduces efficiency on rough substrates. Removal challenges arise from strong bonding, so multiple passes become necessary for complete clearance. On conductive surfaces, contamination insulates and alters thermal response; on delicate optics, it persists and demands precise control to avoid damage. Treatment follows adjustment of parameters, thus enhances removal without residue. Surface after cleaning exhibits smoothness, yet traces still linger in crevices. This behavior demonstrates material-specific resistance, confirming need for tailored approaches in applications.
