Abstract
A method and an apparatus serve for treating workpieces with a treating liquid, in particular for cleaning metallic workpieces prior to a heat-treatment to be performed thereafter. The workpieces are introduced into a washing vessel. The washing vessel is then closed air-tight. A vacuum is then generated in the washing vessel. Further, a duct is opened between the washing vessel and a tank containing the treating liquid. For filling the washing vessel, the vacuum is adjusted to a level such that the treating liquid is drawn into the washing vessel under the action of the vacuum.
