FIELD: technological processes.
SUBSTANCE: invention is related to the field of surfaces protection against destructive processes of anthropogenic and climatic nature, namely, to method of liquid blasting of surfaces from different depositions of anthropogenic and climatic nature, also from ice formation. Method is characterized by application of gas-abrasive jet that consists of mixture of air, nitrogen, water vapors and ice crystals, at that jet characteristics provide behavior of processes of thermodynamic and abrasive destruction of deposition body by means of setting temperature gradient in jet in interval from 100 to 150°C per second, and function of soft abrasive is performed by ice crystals of controlled mass.
EFFECT: provides reduction of environment pollution and damage of surface layer of cleaning object material.
