Stale Bread for Cleaning Soiled Paper.
Wipe the paper with a clean cloth. Cut a loaf of stale bread in two, lengthwise, and rub the bread over the paper, making long strokes straight up and down. When the bread becomes soiled, cut off a thin slice, and continue the work with the clean surface. A large room may require the use of two or three loaves.
Edges of books, margins of pictures, and other things may be cleaned in the same way.
