OIL STAINS IN SILKS AND OTHER FABRICS.
Benzine is most effectual, not only for silk, but for any other material whatever. It can be procured from any druggist. By simply covering both sides of greased silk with magnesia, and allowing it to remain for a few hours, the oil is absorbed by the powder. Should the first application be insufficient, it may be repeated, and even rubbed in with the hand. Should the silk be Tussah or Indian silk, it will wash.
To remove an acid stain on violet silk: Brush the discoloration with tincture of iodine, then saturate the spot well with a solution of hyposulphite of soda, and dry gradually. This restores the original color perfectly.
Muriatic acid is successfully used for removing ink stains and iron mold on a number of colors which it does not attack.
Sulphurous acid is only employed for whitening undyed goods, straw hats, etc., and for removing the stains of certain fruits on silks and woolens. Sulphurous gas is also used for this purpose, but the liquid gas is safer.
Oxalic acid is used for removing ink and rust stains, and remnants of mud stains, which do not yield to other deterrents. It may also be used for destroying the stains of fruits and astringent juices, and old stains of urine. However, its use is limited to white goods, as it attacks fugitive colors and even light shades of those reputed to be fast. The best method of applying it is to dissolve it in cold or luke-warm water, to let it remain a moment upon the spot, and then rub it with the fingers. Wash out in clear, warm water immediately.
Citric acid serves to revive and brighten certain colors, especially greens and yellows. It restores scarlets which have been turned to a crimson by the action of alkalies. Acetic acid or tartaric acid may be used instead.
Where it is feared that soap may change the color of an article, as, for instance, scarlet hosiery or lilac print, if the garment be not badly soiled, it may be cleansed by washing without soap in water in which pared potatoes have been boiled. This method will also prevent color from running in washing prints.
To prevent blue from running into a white ground, dissolve a teaspoonful of copperas in a pailful of soft water, add a piece of lime the size of an acorn, and soak the garments in this water two hours before washing. To keep colors from running in washing black prints, put a teaspoon of black pepper in the first water.
