Anodizing Layer Irregularities Contamination

Anodizing defects, they form on aluminum surfaces during electrochemical oxidation when electrolyte imbalances cause pitting, staining, and uneven oxide layers. This contamination embeds deeply with strong adhesion to the substrate, thus differs from loose particles by altering surface integrity permanently and resists mechanical scraping so risks base material damage in removal attempts. Laser cleaning succeeds here, targeted pulses vaporize defects selectively and surface already regains uniformity following treatment.
