Abstract

Articles which require the removal of an adhering substance, such as residue of a galvanizing bath, are rinsed by spraying an aqueous rinsing agent against them repeatedly. Each spraying interval is followed by a run-off interval during which the sprayed-on rinsing agent can run off the articles. The length of the run-off intervals is equal to, or greater than, the length of the spraying intervals.
