The surface cleaning process takes place with the use of high-pressure cleaning devices that use water or other abrasive materials as a cleaning medium, e.g. spherical steel shot. The technology that uses the dynamic action of a high-energy water jet is called hydrodynamic cleaning. In this metal shot blasting process, the kinetic energy of the shot or other abrasive under high pressure is used. The elements to be cleaned are swept by the abrasive. The advantage of metal shot blasting is precision, speed, the possibility of processing large-size elements and the possibility of processing details that cannot be cleaned by other methods.
