FIELD: process engineering.
SUBSTANCE: invention relates to cleaning of individual protection means, sporting equipment and appliances, particularly, hockey protective equipment. Proposed method comprises precleaning of protective equipment in two ultrasound units. First unit is used for processing in water solution of non-polluting detergent of 50-100 g/l concentration and temperature of 30-40°C with application of travelling ultrasound field of 20-25 W/l intensity for 30-60 minutes with cyclic bubbling of aid solution by air at P = 0.02-0.05 MPa. Second unit makes cleaning in clean water at 30-40°C with application of travelling ultrasound field of 20-25 W/l intensity for 10-30 minutes with cyclic air bubbling at P = 0.02-0.05 MPa with further flushing in running water with simultaneous bubbling.
EFFECT: cleaning without mechanical processing, higher efficiency of all contaminants.
