Abstract

The invention relates to a method for treating at least a part of an object surface by means of a treatment solution (12), wherein the treatment solution (12) contains water and a source of negatively charged chlorine ions, and wherein chlorine gas (26) is provided in the treatment solution (12) by means of electrolysis. The invention also relates to a device for treating at least a part of an object surface, comprising a process tank (10; 60; 80), in which are arranged a treatment solution (12), chlorine gas dissolved in the treatment solution (12), electrodes (14, 16; 85, 86) of different polarity arranged in the treatment solution (12) and a current source (18) which is connected to the electrodes (14, 16; 85, 86) in an electrically conductive manner.
