FIELD: technological processes.
SUBSTANCE: method is based on the impact of n≥3 cavitating jets of water under pressure with the expansion of the cavitating jets in the direction of the surface being cleaned at an angle α=15-70° with creating a set of local impact zones thereon. The axes of the cavitating water jets are oriented with respect to the normal to the surface being cleaned at an angle β=0-20° with forming non-overlapping circular and elliptical impact zones on the surface being cleaned, with the contact of the edges of local impact zones and providing the maximum coverage area of the surface being cleaned by said local impact zones. The surface being cleaned is subjected to pulse impact with the cavitating water jets with a change in the pulse repetition rate till bringing into resonance layered deposits on the surface being cleaned.
EFFECT: increasing the efficiency and productivity of the cleaning process due to increasing the total area of the portion to be treated.
