126. To Remove Oil Stains.

When there are oil spots upon goods, and so fixed or dried in, that steeping in an alkaline lye will not remove them, rub a little soft soap upon the stain, and let it remain for an hour, then rub gently with the hand in a lather of soap, slightly warmed, and wash in water; for cotton, a little caustic lye will do equally well, but the soap is preferable, and seldom fails. It is essential that all oil or grease be removed before dyeing.

127. To Remove Iron Stains.

Take a little hydrochloric acid in a basin or saucer, and make it slightly warm, then dip the iron stain into the acid for about 1 minute, which will dissolve the oxide of iron; the cloth must be well washed from this, first in water, then in a little soda and water, so as to remove all trace of acid. A little oxalic acid may be used instead of hydrochloric, but More time is required, and with old fixed spots is not so effective. The same precautions are necessary in washing out the acid, as oxalic acid dried in the cloth injures it.

128. To Remove Mildew from Cotton.

Proceed with the stains by rubbing in soap or steeping in a little soda, washing, and then steeping in bleaching liquor (see No. 104), sor by putting a wine-glassful of the stock liquor (see No. 101) in 1 pint of water; after wards wash, pass through a sour (see No 105), and wash again.

129. To Remove Indelible-Ink Marks.

Steep in a little chlorine water or a weak solution of bleaching liquor (see No. 104), for about half an hour, then wash in ammonia water, which will obliterate the stain; then wash in clear water. They may also be removed by spreading the cloth with the ink marks over a basin filled with hot water; then moisten the ink marks with tincture of iodine, and immediately after take a feather and moisten the parts stained by the iodine with a solution of hyposulphate of soda, or caustic potassa or soda, until the color is removed; then let the cloth dip in the hot water; after a while wash well and dry.
