Dry ice blasting exclusively uses dry ice for graffiti removal, which is blasted onto the surface to be treated at a low pressure of 0.5 to 16.0 bar. The graffiti comes off primarily due to the cold shock, because the dry ice has a temperature of about minus 80 degrees. Dry ice is CO2. However, if one now believes that the environment is burdened by additional CO2 emissions, this is a fallacy. Because it is merely a by-product of industry that is recycled, so to speak. Another advantage is that no harmful chemicals or water are used. In contrast to abrasive methods or methods using high pressure, dry ice is not as aggressive and is therefore also used for sensitive surfaces. However, damage to the façade is still possible. Of course, less sensitive surfaces such as plaster, concrete, bricks or clinker can also be cleaned from graffiti using this method. The storage costs for dry ice are quite high. Above all, the dry ice must be stored at -80 degrees. This only works for a short time.
