Wax Coating Buildup Contamination

Wax-buildup contamination arises from paraffin, carnauba, and synthetic deposits in protective coatings and polishes, and it accumulates layer by layer on surfaces. This buildup, hydrophobic and soft in texture, distinguishes itself from greasy oils or dust by even spreading and resistance to solvents. On metals such as steel and aluminum, it clings tightly yet vaporizes readily under laser pulse, thus challenges like incomplete removal diminish, and laser cleaning succeeds through precise ablation without substrate harm.
