Pollen Accumulation Contamination

Pollen-deposit contamination, it arises from fine plant residues transported by wind and humidity, which settle on surfaces to form tenacious organic layers. Unlike inorganic dusts that lack biological adhesion, this deposit exhibits a granular texture, persists under exposure, and on crown glass creates uneven films resisting wipes, while on steel and aluminum it shows similar hold, dependent from surface smoothness that influences variability across glasses and metals. Removal challenges stem from its tenacity against mechanical methods, yet laser cleaning proves effective, as it ablates organics selectively, sparing the substrates.
