FIELD: foundry. SUBSTANCE: method includes impregnation of core with water, cooling down to temperature of minus 160 to minus 180 C with simultaneous loading with pressure at rate preventing freezing of water in ceramic pores up to pressure of 220 MPa. Device for realization of method has plate on which cylinder with warmth-keeping jacket is installed on isolating spacer. Fixed plunger is located in cylinder. Moved over guide columns is crosspiece to which rod of hydraulic cylinder is attached. Rod ends has grips for keeping casting to be cleaned. EFFECT: higher efficiency. 4 cl, 1 dwg
