A technique has been developed that takes into account the effect of the ultrasonic vibration amplitude and the time of exposure on the process of removing contaminants. The results of experimental studies are presented that confirm that increasing the exposure time contributes to increasing the washed scale mass and decreasing the time of liquid outflow. The developed regression model describes well the changes in the mass of washed scale, which is confirmed by a high coefficient of determination and correlation. The obtained results allow for optimizing the parameters of the ultrasonic cleaning process, increasing its efficiency and reducing the risk of damage to the structural elements of the radiator. ER
