Keep an oyster-shell in your tea-kettle, and it will prevent the formation of a crust on the inside of it, by attracting the stony particles to itself.
407. To remove Stains from Broadcloth.
Take an ounce of pipe clay that has been ground fine, and mix it with twelve drops of alcohol, and the same quantity of spirits of turpentine. Whenever you wish to remove any stains from cloth, moisten a little of this mixture with alcohol, and rub it on the spots. Let it remain till dry, then rub it off with a woollen cloth, and the spots will disappear.
408. To extract Paint from Cotton, Silk, and Woollen Goods.
Saturate the spot with spirits of turpentine, and let it remain several hours, then rub it between the hands. It will crumble away, without injuring either the color or texture of the article.
409. To remove Black Stains on Scarlet Woollen Goods.
Mix tartaric with water, to give it a pleasant acid taste, then saturate the black spots with it, taking care not to have it touch the clean part of the garment. Rinse the spots immediately, in fair water. Weak pearl-ash water is good to remove stains that are produced by acids.
410. To extract Grease from Silks, Paper, Woollen Goods, and Floors.
To remove grease spots from goods and paper, grate on them, very thick, French chalk, (common chalk will answer, but is not as good as the French chalk.) Cover the spots with brown paper, and set on a moderately warm iron, and let it remain till cold. Care must be taken not to have the iron so hot as to scorch or change the color of the cloth. If the grease does not appear to be out on removing the iron, grate on more chalk, heat the iron again, and put it on. Repeat the process till the grease is entirely out. Strong pearl-ash water, mixed with sand, and rubbed on grease spots in floors, is one of the most effective things that can be used to extract the grease.
