This is the composition commonly, but erroneously called salt of lemon, and is excellent for removing ink and other stains from the hands, and for taking ink spots out of white clothes. Pound together in a marble mortar an ounce of salt of sorrel, and an ounce of the best cream of tartar, mixing them thoroughly. Then put it in little wooden boxes or covered gallipots, and rub it on your hands when they are stained, washing them in cold water, and using the acid salt instead of soap; a very small quantity will immediately remove the stain. In applying it to linen or muslin that is spotted with ink or fruit juice, hold the stained part tightly stretched over a cup or bowl of boiling water. Then with your finger rub on the acid salt till the stain disappears. It must always be done before the article is washed.
This mixture costs about twenty-five cents, and the above quantity (if kept dry) will be sufficient for a year or more.
Ink stains may frequently be taken out of white clothes by rubbing on (before they go to the wash) some bits of cold tallow picked from the bottom of a mould candle. Leave the tallow sticking on in a lump, and when the article comes from the wash, it will generally be found that the spot has disappeared. This experiment is so easy and so generally successful that it is always worth trying. When it fails, it is in consequence of some peculiarity in the composition of the ink.
