Abstract
A device for cleaning ink pen points of the type which are removable from an ink pen. The device includes an upper section and a lower section complementally engagable with each other, so as to support the pen point in a vertical attitude for sequential attack by cleaning water and drying air. The device includes a jet pump portion actuated by the cleaning water, so as to advance drying air through the pen point. The device is characterized by its mechanical simplicity, yet extreme effectiveness in cleaning artists and stylographic drafting pen points.
