The material requiring treatment should first be soaked in clean, warm water, the superfluous moisture removed, and the fabric spread over a clean cloth. Now allow a few minims of liquor ammoniæ fortis, specific gravity 0.891, to drop on the ink spot, then saturate a tiny tuft of absorbent cotton-wool with acidum phosphoricum dilutum, B. P., and apply repeatedly and with firm pressure over the stain; repeat the procedure two or three times, and finally rinse well in warm water, afterwards drying in the sun, when every trace of ink will have vanished. This method is equally reliable for old and fresh ink stains, is rapid in action, and will not injure the most delicate fabric.

To remove ink spots the fabric is soaked in warm water, then it is squeezed out and spread upon a clean piece of linen. Now apply a few drops of liquid ammonia of a specific gravity of 0.891 to the spot, and dab it next with a wad of cotton which has been saturated with dilute phosphoric acid. After repeating the process several times and drying the piece in the sun, the ink spot will have disappeared without leaving the slightest trace.

Ink spots may be removed by the following mixture:

Oxalic acid......... 10 parts

Stannic chloride .... 2 parts

Acetic acid......... 5 parts

Water to make...... 500 parts

Mix.

The customary method of cleansing ink spots is to use oxalic acid. Thick blotting paper is soaked in a concentrated solution and dried. It is then laid immediately on the blot, and in many instances will take the latter out without leaving a trace behind. In more stubborn cases the cloth is dipped in boiling water and rubbed with crystals of oxalic acid, after which it is soaked in a weak solution of chloride of lime—say 1 ounce to a quart of water. Under such circumstances the linen should be thoroughly rinsed in several waters afterwards. Oxalic acid is undesirable for certain fabrics because it removes the color.

V

Here is a more harmless method: Equal parts of cream of tartar and citric acid, powdered fine, and mixed together. This forms the " salts of lemon " sold by druggists. Procure a hot dinner plate, lay the part stained in the plate, and moisten with hot water; next rub in the above powder with the bowl of a spoon until the stains disappear; then rinse in clean water and dry.

To Remove Red (Aniline) Ink

Stains of red anilines, except eosine, are at once removed by moistening with alcohol of 94 per cent, acidulated with acetic acid. Eosine does not disappear so easily. The amount of acetic acid to be used is ascertained by adding it, drop by drop, to the alcohol, testing the mixture from time to time, until when dropped on the stain, the latter at once disappears.
