Ice-blasting – this cleaning involves shooting of small dry ice particles (with the size of a rice grain) with a high speed and under a high pressure. Using a temperature of about -73 degrees, the dry ice is cooling down the surface, which makes the dirty layer fragile and brittle.
Abrasive blasting – this technique is having not only cleaning effect, but will also improve the qualities of the external layer. Due to this blasting a good paste can become even better.
Sand-jet treatment – the surface is treated with a high speed jet washing with sand under a high air or steam pressure.
