Adhesive Residue / Tape Marks Contamination

Adhesive-residue contamination forms during shipping or labeling processes, and clings tenaciously to metals and plastics. Unlike dust that brushes away easily or oils that evaporate quickly, layer hardens over time so tackiness persists after exposure. During cleaning, bonds resist solvents, so gentle methods apply to prevent surface damage. Buildup is observed as sticky films, distinct because it demands careful removal without scratching.
