FIELD: technological processes.
SUBSTANCE: invention is related to methods for cleaning of metal items from technological contaminants that are accumulated on their surface in process of manufacturing, and operational contaminants that occur in process of their dedicated use and storage. Method is intended for ultrasonic flow cleaning of metal items in aqueous solutions with specific acoustic resistance that is not less than in water, at the same time level of sound pressure in solution is established not lower than five decibels relative to elastic oscillations with pressure amplitude that equals to one atmosphere.
EFFECT: identical high quality of cleaning at various chemical composition, content of dissolved detergents and contamination of aqueous solutions, which makes it possible to extend life of solutions application and to expand field of cleaning application.
