Mix 2d. worth of mercury and \d. of prepared chalk in a saucer with a little warm water, and with a small piece of leather rub the tarnished article until the polish is restored.
N.B.-Mercury, if used often, is apt to remove the plate.
SILVER LACE can be easily brightened by the application of a little dry, powdered magnesia, which is simply rubbed on and allowed to remain for a few hours, then brushed off with a clean, dry plate brush, or rubbed with a flannel dipped in spirits of wine.
WHITING, when precipitated so as to avoid any danger of scratching through the presence of grit, is to be thoroughly recommended as being cheap, safe, and efficacious.
Many plate powders contain mercury, which is very injurious to any kind of electro-plate; quicksilver causes silver to become brittle and easily broken.
Non-mercurial rouge is very good. Many pink powders are simply precipitated whiting, coloured with a little jewellers' rouge, which can easily be procured at 2d. an ounce.
DISCOLOURED silver may be readily restored by making a paste of hartshorn powder (1d. per oz.) and spirit of wine. This produces a good polish, which perhaps lasts longer than that produced by use of whiting. Ammonia is also a good agent for removing tarnish; in fact, gin, or any kind of spirit, is effectual; but methylated spirit is the cheapest form.
WHITING is simply chalk pounded into a rough powder.
Tie some whiting loosely in fine muslin (old muslin castor sugar bags answer the purpose); fasten it to the handle of a jug, allowing the part of the muslin containing the whiting to be inside the jug; pour over it cold water, taking care that it covers the whiting; let it stand all night, or, if wanted for immediate use, keep moving the bag till all has passed through; then pour off all the clear water. Let the sediment (which is the whiting) dry on plates on the rack or in a warm place. Keep in a box away from the dust.
Boil for five minutes some soft old rags in 1 pint of new milk to which has been added 1 oz. of hartshorn powder; wring out immediately, and dry before the fire, keeping the cloths with the cleaning materials for future use.
SILVER should always, after use, be washed in very hot soapy water; a little ammonia helps to make it bright. After being rinsed in hot water it should be placed on a tray, taking care that it is put in such a way as to avoid scratching. It should be dried immediately; as if allowed to remain wet for long water marks are often formed. After drying, it should be rubbed with a chamois leather, which should be kept in the baize-lined wicker plate basket. These baskets, costing about 4/6, contain divisions for the various articles, which should always be returned to their respective places. When the weekly silver cleaning takes place, the basket should be emptied, turned upside down and gently tapped, also brushed to remove any dust. The silver should all be counted to see that none is missing; a written list may conveniently be kept fastened with drawing pins on the inside of the door of the butler's pantry.
TIN. Tin can be cleaned very satisfactorily, in the same way as silver, by using water and whiting made into a paste, then polishing it with dry whiting.
