Presence of the pollutants in various industrial sectors is undesired. Residual dirt may lead to serious consequences
like devices overheating, damage, increased risk of fire or efficiency drop. That is why wide range of industrial pollutants
cleaning methods were developed and used. Among the physical blasting methods the dry ice blasting can be enumerated. This
method consists of polluted surface cleaning with the high-speed air-dry ice mixture. Blasting process is supported by heat
transfer related phenomena and carbon dioxide sublimation which correspond to easier dirt removal. Described method is
dedicated for various pollutants types removal form inorganic dust up to oily organic, which was confirmed in the experiments
described in the paper.
