Nickel can be cleaned with soap and water and polished with ungritty, well devised polishes. Never use anything that will scratch it. Boil iron in soda and water, rub with some good powder with a bit of scratch in it. Use hot soap suds. Dry while it is hot. Do not use soap on aluminum; there are regular aluminum cleaners on the market. Occasionally only use a little acid, such as lemon or tomato diluted. Never use soda. Boil agate in soda water. Wash in hot soap suds and dry. Use dilute oxalic acid for cleaning brass, fine powder, plenty of water. Polish with metal polish which abounds on the present market. Tin can be cleaned with soda and water, but do not leave it in this solution long, as the alkali will eat the tin. Wash and dry at once or you will have rust on your tin ware. The silver story is long but well known. The only thing not to do is to use gritty powders that will scratch. Wash your silver after cleaning, as the cleaning mixtures do not make good appetizers. In caring for electric ironers and washing machines, first of all read the directions that come with them. Oil as they tell you or don’t oil; too much oil is bad and too little is bad. Do not overload (with clothes) your cylinder or your drum; some motors rebel and there is trouble. When buying your washer be sure to tell the electrician what kind of electricity you consume, whether it is A C or D C; also the voltage of your circuit. This applies to all electric machinery. Don’t leave your electricity on when you are not using a device. If you do in the case of the iron, you will have fires and all kinds of trouble. Don’t blame the machine for faults of your own. Remember in the case of the electrical ironer that heat is hot and that if you leave a piece of goods on the roll and the motor going you will burn your article. These things are cleaned with warm water and polished and dusted in accordance with the ordinary metal needs. There is little to say about their upkeep except what has been said about other devices. Follow the directions of the makers; they know the exigencies of their offspring. Soft cloths and warm water are best for cleaning white wood enamel. Soaps yellow the enamel, so a few drops of ammonia added to a pail of water will help banish grease. Warm water and soap or soda and warm water will clean off marble tops. In the long life-assurance of metals generally, it must be born in mind that in order to keep them clean and bright things must be used that will not scratch, corrode or roughen--or at least do as little of these things as possible. In the case of silver cleaning the aluminum pan method is best because there is less corrosion and less roughening.
