Ink.
While the stains are yet wet upon the carpet, sponge them with skim-milk thoroughly. Then wash out the milk with a clean sponge dipped again and again in fair water, cold. Exchange this presently for warm; then rub dry with a cloth. If the stain is upon any article of clothing, or table, or bed linen, wash in the milk well, afterward in the water.
Dry ink stains can be removed from white cloth by oxalic acid, or lemon-juice and salt.
