Take a newspaper, or a part of one, according to the size of the glass. Fold it small, and dip it into a basin of clean, cold water. When thoroughly wetted, squeeze it out in your hand, as you would a sponge; and then rub it, hard, all over the face of the glass; taking care that it is not so wet that the moisture will stream down the glass. Also, if any drops get beneath the frame, and behind the glass, they will remain there, in bubbles, and cannot be dislodged, without removing the board at the back. There is no danger of any such accidents, if the newspaper is merely moistened, or damped throughout; without being so wet as to drip. After the glass has been well rubbed, with the damp paper, let it rest a minute. Then go over it with a fresh newspaper, (folded small in your hand,) till it looks clear and bright; which it will, almost immediately. Finish with a fresh piece of newspaper, thoroughly dry.

This method, simple as it is, will be found, on trial, the nest and most expeditious way of cleaning mirrors, or any plate-glass; giving a clearness and polish, that cannot be so soon produced by any other process. The inside of window-panes may be cleaned in this manner; the windows having been first washed on the outside. Also, the glasses of spectacles, etc. The glass globe of a lamp may thus be cleaned with newspapers.

The efficacy is attributed to the materials used in making the printing-ink.
