217. _To remove Stains from Silks._--Stains produced by vinegar, lemon-juice, oil of vitriol, or other sharp corrosives, may often be removed from silks by mixing a little pearlash with soap-lather and passing the silk through them. Spirits of hartshorn will also often restore the color. 218. _To dip Rusty Black Silk._--Boil logwood and water half an hour, in which simmer the silk for the same time; then take it out, and put into the dye a little blue vitriol, or green copperas; cool it, and simmer the silk in it for half an hour. Or, boil a handful of fig-leaves in two quarts of water until it be reduced to one pint; squeeze the leaves, and bottle the liquor for use. When wanted, sponge the silk with it. The word _Poison_ should be written on the bottle. 219. _Black Reviver._--Upon two ounces of powdered logwood, and half an ounce of green copperas, pour three pints of boiling water: let it stand till cold, when strain for use, by sponging the faded stuff with it. To revive black cloth, boil it with logwood in water for half an hour, the cloth having been previously cleaned, dipped in warm water, and squeezed dry; next, take out the cloth, add a small piece of green copperas, and boil it another half hour; then hang it in the air an hour or two, rinse it twice or thrice in cold water, dry it, and finish it with a soft brush, over which two or three drops of olive oil have been rubbed. 220. _White Satin._--Stone blue and flannel will make white satin look nearly new, especially if rubbed afterwards with crumbs of bread. 221. _Blond Lace._--When blond lace gets tumbled, breathing upon it, and afterwards shaking it, will be found to answer the purpose of an iron, without chance of making the lace look yellow, as it probably would be by the use of an iron. There is no necessity for unpicking the lace. 222. _To raise the Surface or Pile of Velvet when pressed down._--Warm a smoothing-iron moderately, and cover it with a wet cloth, and hold it under the velvet; the vapor arising from the heated cloth will raise the pile of the velvet, with the assistance of a rush whisk. 223. _To remove Grease or Oil Paint from Cloth._--Moisten them with a few drops of concentrated solution of subcarbonate of potash; rub the spot between the fingers, and then wash the spot with a little warm water. 224. _Another way._--To remove oil paint, rub the part with a bit of flannel dipped in spirits of wine or turpentine. 225. _Spots from Woollen Cloths._--Fullers' earth, or tobacco pipe-clay, being put wet on an oil spot, absorbs the oil as the water evaporates, and leaves the vegetable or animal fibres of cloth clean, on being beaten or brushed out. When the spot is occasioned by tallow or wax, it is necessary to heat the part cautiously by an iron or the fire, while the cloth is drying. In some kinds of goods, blotting paper, bran, or raw starch, may be used with advantage.
