Other appliances which are used for wiping walls and floors are string mops, broom bags, and heavy cloths attached to a mop handle. String mops scatter lint and it is impossible to wash them entirely clean. Broom bags are good because they can be washed easily, and because they make a broom into a combination appliance useful either for sweeping or wiping. They are said to be better made with a ruffle. Mop handles with attachments to hold the cloths are easily obtainable and much better for all purposes than string mops. In choosing one, see that the attachment is neither heavy nor intricate. Cloths can be easily attached to a mop stick if a deep groove is cut in the stick two or three inches from the end. Hold the stick with the grooved end up. Lay over it two or three heavy cloths--in the way one would put an unfolded handkerchief over the end of one's finger. Draw them down and tie a string tightly round them in the groove. Then reverse the handle and the mop is ready for use. Patent handles are better than this homely contrivance in all but one respect: in using them one must guard against striking furniture or baseboards with the metal piece which holds the cloth. Here are a few important principles of cleaning. 1. Prepare the place which is to be cleaned. 2. Begin at the top. A house is cleaned from garret to cellar, a room from ceiling to floor, a staircase from top to bottom. 3. Do not flap round with a cloth or a feather duster. The object of cleaning is to remove dust, getting as little into the air as possible. 4. All necessary shaking and brushing must be done before the floor is cleaned; afterward, only _wiping_ should be done. We will now go over the process of cleaning a room as if we were prompting ourselves for the actual work. Remove the plants to the sink. Remove and carefully dust the ornaments, putting them on a tray which can be carried into an adjoining room, or put them on a stationary piece of furniture, which has been dusted to receive them, and cover with a dusting sheet. Shut the doors into adjoining rooms. Open the windows. Dust the shades and roll to the top of the windows. Shake, brush and cover the curtains. Remove the upholstered furniture and rugs if possible. If not, brush the furniture and cover it, sweep and roll the rugs. If there is a fireplace in the room remove the ashes and lay the fire. Wipe the ceiling, walls, woodwork, light fixtures and pictures. Wipe the floor, not forgetting the baseboards, or sweep the carpet. Whatever is done to the floor is the climax of the cleaning. After that we restore the room to order. This is the period when everything should be done by wiping. Clean rugs and furniture which have been put outdoors. Wipe furniture, mirrors, picture-glasses, windows and tiles. Restore the rugs, furniture and ornaments to their places.
