A sink placed at a height that admits of an erect position while washing dishes, [Footnote 1: In case it is necessary for one to wash dishes at a sink which is placed too low, the dish-pan may be raised by placing it on an inverted pan or on a sink-rack, which may be purchased for this purpose.] and equipped with two draining boards, one on each side of the sink, or with one draining board on the left side; dish and draining pans; dish-drainer (see Figures 4 and 5); dish-rack (see Figures 6 and 7); dish- mop (see Figure 3); wire dish-cloth or pot-scraper (see Figure 3); dish- cloths (not rags); dish-towels; rack for drying cloths and towels; soap- holder (see Figure 3) or can of powdered soap; can of scouring soap and a large cork for scouring; tissue paper or newspapers cut in convenient size for use; scrubbing-brush; bottle-brush (see Figure 3); rack made of slats for drying brushes (see Figure 2).

PREPARING DISHES FOR WASHING.—If possible, as soon as serving dishes, i.e. dishes used at the dining table, are soiled, scrape away bits of food from them. The scraping may be done with: (a) a piece of soft paper, (b) plate-scraper (see Figure 3), (c) a knife or spoon. The latter is doubtless the most commonly used for dish scraping, but it is less efficient and may scratch china. If it is impossible to wash dishes soon after soiling, let them soak in water until they can be washed.

Note the draining board on each side of the sink, the dish-cupboard in the upper left corner, and the rack for drying brushes below the sink.]

Cooking utensils need special care before washing, especially if they have held greasy foods. "Oil and water do not mix!" The grease from dish-water often collects in the drain-pipe and prevents or retards the drainage of waste water. This often means expensive plumber's bills and great inconvenience. Bear in mind the following cautions Before putting a utensil which has held fat into the dish-water, always wipe it carefully with a piece of paper. After wiping most of the grease from a pan or kettle, the remaining fat can be entirely removed by filling the utensil with hot water and then adding washing-soda. Boil the solution a few minutes. Fat and washing-soda react and form soap; hence the effectiveness of this method (See Experiment 34) (This method should not be applied to aluminum utensils; washing-soda or any alkaline substance makes a dark stain on aluminum)

Utensils used in cooking can generally be washed with greater efficiency if they are soaked before washing. Fill each dish or pan with water, using cold water for all utensils which have held milk, cream, eggs, flour, or starch, and hot water for all dishes having contained sugar or sirup.

ARRANGING DISHES.—Arrange dishes and all the requisite dish-washing utensils in convenient order for washing, placing all of one kind of dishes together. Also place the dishes to be washed at the right of the dish-pan. Wash them and place the washed dishes at the left of the pan. A dish-washer invariably holds a dish that is being washed in her left hand and the dish-cloth or mop in her right hand. That there may be no unnecessary motions, the dishes should be placed to drain after washing at the left of the dish-pan. In this way there is no crossing of the left hand over the right arm as there would be if the washed dishes were placed at the right of the dish-pan. A cupboard located above the draining board at the left makes the storing of dishes an efficient process (see Figure 2).

WASHING AND SCOURING DISHES AND UTENSILS.—Fill the dish-pan about two thirds full of hot water. "Soap" the water before placing the dishes in the pan; use soap-powder, a soap-holder, or a bar of soap. If the latter is used, do not allow it to remain in the water. Fill another pan about two thirds full of hot water for rinsing the dishes. A wire basket may be placed in the rinsing pan.
