Abstract

A radiator having a header is cleaned by at least partially immersing the radiator in a cleaning liquid so that the header is immersed in the cleaning liquid and then applying ultrasonic energy to the cleaning liquid at an energy sufficient to cause cavitation of the liquid. The header is oriented in a direction toward the source of the ultrasonic energy, whereby the header is in closer proximity to the energy source than the remainder of the radiator, so that the ultrasonic energy is initially directed onto the face of the header.
