To Clean Black Cloth Clothes Clean the garments well, then boil four ounces of logwood in a boiler or copper containing two or three gallons of water for half an hour; dip the clothes in warm water and squeeze dry, then put them into the copper and boil for half an hour. Take them out, and add three drachms of sulphate of iron; boil for half an hour, then take them out and hang them up for an hour or two; take them down, rinse them thrice in cold water, dry well, and rub with a soft brush which has had a few drops of olive oil applied to its surface. If the clothes are threadbare about the elbows, cuffs, &c., raise the nap with a teasel or half worn hatter's card, filled with flocks, and when sufficiently raised, lay the nap the right way with a hard brush.
