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 at- tacks 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 hike-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 teaspoonful of black pepper in the first water.
Salt or beef's gall in the water helps to set black. A tablespoon- ful of spirits of turpentine to a gallon of water sets most blues, and alum is very efficacious in setting green. Black or very dark cal- icoes should be stiffened with gum arabic five cents' worth is enough for a dress. If, however, starch is used, the garment should be turned wrong side out.
A simple way to remove grass stains is to spread butter on them, and lay the article in hot sunshine, or wash in alcohol. Fruit stains upon cloth or the hands may be removed by rubbing with the juice of ripe tomatoes. If applied immediately, powdered starch will also take fruit stains out of table linen. Left on the spot for a few hours, it absorbs every trace of the stain.
