Lamp chimneys of various makes are very difficult to clean quickly and thoroughly. The simple device shown in the sketch makes the cleaning process a simple matter. The cleaner is made of a round rubber ball with slits cut in it as shown and then fastened to the end of a stick. When a cloth is placed over the ball it presses evenly against the curved surfaces of the glass. There is no danger of breaking a chimney with this cleaner.
