How does Dry Ice Blasting works?

Thermal effect: The pieces of the dry ice collide with the dirty surface at low-temperature, at -78 degree. The temperature differences crack the dirt. The different materials have different contractility. Because of the sudden onset thermal-shock between the surface and the dirt-causing material terminates the connection.

Kinetic effect: The pieces of dry ice by a compressed air powered ice blasting equipment goes to the surface to be cleaned. The pieces of dry ice leaves the spray gun at 300 m/s speed and bump against to the dirty surface and loosen the dirt-causing material.

Sublimation: The dry ice breaks through the dirt-caused material which needs to be removed and there immediately sublimates, evaporates, causing drastic volume increases which explosively separates the deposits from the surface.
