Laser cleaning is basically blast off the contaminants or impurities on the surface of the target by applying laser pulse directly to them. The great control over power and pulse parameters offer by laser allow user to decide the ablation depth themselves. Which means, not damage will done to the underlying material. Plus it is also a non-contact and non-abrasive cleaning method as no other mediums or chemical solvents are require throughout whole cleaning process.
During the laser cleaning process most the contaminants will vaporised and leaving little waste behind which can be easily counter through suction. And this why laser cleaning is considered environment friendly compare to convention cleaning method such as media blasting or chemical solvents cleaning which will create huge amount of waste that need to be dispose carefully after cleaning .
