1 ball potash, ½ ounce salts of tartar, ½ ounce carbonate of ammonia. Dissolve in 1 gallon warm water, keep on the stove until heated, mix, keep in a jug or bottle well corked. Soak the soiled clothes over night. In the morning put 3 pails of cold water in the boiler, and add to it 1½ bars of soap shaved fine, and 1 cupful of the washing fluid. Put in the clothes least soiled first. Let the water heat up gradually and boil one-half hour, stirring frequently. Take out into a tub of warm water, rub the soiled portions if necessary, rinse and Hue.
½ pound sal-soda, ½ pound borax, ½ ounce gum camphor, ½ pint alcohol, ½ pint turpentine. Dissolve the camphor in the alcohol; pulverize the soda and borax and dissolve in 3 gallons of rain water. Mix the whole together and add 8 gallons more of rain water. It is then ready for use.
Take 1 pint of soft soap, or ½ bar of hard soap, shaved fine, and mix with 1 cupful of the fluid. Make a warm, not hot, suds in a tub and soak the clothes one-half hour, then rub out, rinse, and the work is done. Keep the fluid tightly corked.
4 pounds of the common bar castile soap, shave fine; 4 pounds of common bar soap, shave fine; 3 pounds sal-soda, 8 ounces aqua ammonia. Dissolve all but the ammonia in 2 pailfuls of hot rain water. Let cool. While cooling test the soap, and add as much water as will make it the consistency of good soft soap. When cool this will make about 100 pounds of the best soft soap. Add the ammonia while it is cooling and mix thoroughly.
If any part of this is desired hard, boil the required portion one hour, adding 1 bar soap and ½ pound sal-soda to it. If the soap is wanted white, the castile and other soap must be white. If it should be desirable to scent the hard soap, 4 ounces of bergamot may be added to 50 pounds of soap.
Directions for using either the hard or soft Centennial soap. Soak the clothes in a strong suds made by dissolving the soap; also rub a little on all the soiled spots. Let them stand over night. No wash-board or boiler will be required. Simply rinse out in the morning in two cool waters. The clothes will not be injured. Soak in separate tubs if there is a great difference in quality of clothes.
Make the suds as usual, put into the three pailfuls 2 or 4 tablespoonfuls ammonia, according to the hardness of the water, this whitens the clothes. Boil from ten to twenty minutes, according to the soiled state of the clothes. Rinse in the usual way, rubbing any soiled spots. Many persons wash calicos, flannels and bed quilts in this manner; rinse the flannels in rather warm water. They will not shrink nor turn yellow.
Borax for Washing may be used in the same manner as ammonia. It will not injure the clothes, being a neutral salt while its whitening properties are invaluable. Use a large handful of the borax powder to 10 gallons of the boiling suds.
