The Housekeeper's Handbook of Cleaning #250563

It must be frankly confessed that even in the laboratories where experiments in the applications Of science to household problems are made, not all has been learned that we ought to know. But many tests have been made, some pretty well proved, and many more have been established as probabilities. This book contains the results Of such testing, in both laboratory and home. It deals with the numerous aspects of Cleaning that come within the housekeeper's range. Each housekeeper must do her own testing, for her immediate problems, but this little volume is a sort Of laboratory guide for her to save her time and energy as she goes forth in the daily battle against dirt.
