Abstract
A method for removing solidified ink or varnish from a surface includes applying a cleaning agent to the ink on the surface. The cleaning agent applied to the ink on the surface is substantially solvent-free and water-based and reduces adhesion between the ink and the surface without dissolving the ink. An adhesive side or face of a single-sided or single face adhesive element is applied to the surface. As the adhesive element is removed from the surface, the ink that has been treated with the cleaning agent but is undissolved adheres to the adhesive element and is thus removed from the surface together with the adhesive element without splitting.
