Abstract
An environmentally acceptable cleaning liquid for use in the graphic industry consisting of 90-99% of a vegetable oil, in particular soy oil, and 1-10% of a surfactant emulsifier. The liquid is suitable for removing ink from printing machines where it is capable of replacing the traditional cleaning liquids based on petroleum spirit and aromatic solvents. As the liquid does not contain any health hazardous components it is completely safe to work with, and due to its bio-decomposable character it is disposable without problems. Because of its excellent penetration properties the liquid is also suitable for cleaning off machine parts which otherwise are difficult to clean, e.g. rubber sheets.
