  • Patent number: 5976194
    Abstract: A method and means for cleaning silk fabric for the prompt and efficient removal of stains from silk fabric, for example a stain on a silk tie, without causing visible lasting changes in color and without unpleasant smell. By means of a cleaning tissue, made of, for example, a textile material, essentially in the form of a wet tissue, impregnated with a grease solvent and a neutralizing agent, a stain on a silk tie is easily removed without any traces by rubbing the stain with the tissue, whereby the stain is dissolved by the grease solvent and is absorbed by the tissue, the smell-neutralizing agent preventing any unpleasant smell from spreading. The grease solvent may be a special boiling point spirit of heptane type. The smell-neutralizing agent may be an oil of terpene type, such as lemon oil.
