Important: Safety Warning
This page describes trade processes that use dangerously toxic materials such as cyanide solutions, mercury amalgams, or strong acids. These processes require training, equipment, and precautions far beyond what the text describes.
This page directs the use of hazardous substances — such as benzine, gasoline, lye, or strong acids — for household tasks. These materials are highly flammable, corrosive, or poisonous, and the practices described have caused fires, burns, and poisonings.

Removal of Spots and Stains: Repeat
For Small Articles. -A paper flour sack, to which they may be attached by pins or basting threads, is light, tight, and convenient for bleaching small articles. Put the brimstone in a saucer and cover with a tin funnel REMOVAL OF SPOTS AND STAINS so that the fumes will be directed up into the bag. Repeat if necessary, hang the articles out of doors until the odor has passed away, and wash as usual. This method is suitable for flannels, woolen hose, yarn, and also for silk, straw, and straw goods.
To Bleach with Oxalic Acid. - Dissolve 1 ounce of oxalic acid in 1 gallon of boiling water; allow this to cool until it will bear the hands. Immerse the articles and let them steep for an hour or more, rinse thoroughly. and dry. Repeat if necessary.
To Bleach Flannel. - Dissolve 1 ounce of powdered ammonia and 1 ounce of salt in 2 quarts of water.
Soak the articles in this for an hour or more.
Or dissolve 2 ounces of bisulphite of soda in 1 gallon of water acidulated slightly with hydrochloric acid. To Bleach Silk.-Nearly one half, by weight (30 to 40 per cent), of the fibers of silk consists of various gums and coloring matter. in The operation of bleaching consists (1) Boiling the silks in soapsuds, with the addition of bran, to remove these impurities; (2) exposing them to sulphurous-acid gas.
Or boil in soapsuds, rinse, and expose to the sun. Or bleach with the fumes of sulphur.
To Bleach Feathers. - Make a dilute solution of bicarbonate of potassium, I part to 10 parts of water, slightly acidulated with nitric acid, 1 fluid ounce to the gallon. Immerse the feathers for 3 or 4 hours. Afterwards rinse in clear water, slightly acidulated with sulphuric acid, 1 fluid ounce to the gallon.
To Bleach Straw Goods. - Substances recommended for bleaching straw and straw goods, including straw hats, are sulphurous acid (i. e., fumes of burning sulphur), chlorine water (or chloride of lime), citric acid, and oxalic acid. Straw goods must be prepared for bleaching by scrubbing with lukewarm soap and water.
The safest and best method of bleaching straw is perhaps by means of the fumes of burning sulphur. This method is employed by manufacturers and milliners to bleach hats and bonnets. All bands and trimmings must first be removed.
Or apply chlorine water with a sponge, cloth, or brush. Afterwards rinse in clear water containing hyposulphite of soda. Or make a paste of corn meal and a solution of oxalic acid in water.
Spread this on the hat, allow it to dry, and remove by brushing.
Or apply a strong solution of oxalic acid and water, and rinse. Or immerse in a weak solution of chloride of lime-2 ounces to 1 gallon of water. Rinse in water containing hyposulphite of soda. Or make a paste of flowers of sulphur. Or pulverize brimstone with water. Cover with this, and expose to direct sunshine until dry. Repeat if necessary. Remove the sulphur by brushing. This is simple and successful.
To Bleach Straw Braid. Dissolve 6 ounces of chloride of lime in a gallon of water. (1) Dip the goods in this for thirty minutes. (2) Dip in clear water acidulated with muriatic or sulphuric acid at the rate of 1 fluid ounce to the gallon. (3) Rinse in clear water containing 1 ounce of hyposulphite of soda to the gallon.
Or dip in weak soapsuds and expose to the fumes of burning sulphur. To Prevent White Goods from Fading. - If a suitable lawn or grassplot is available, spread white garments on the grass to dry during the warm months of the year. This is more convenient than fastening to a line and keeps the garments always bleached.
