Oxalic acid  10 parts
Stannic chloride   2 parts
Acetic acid   5 parts
Water to make 500 parts

Mix.

IV.—The customary method of cleansing ink spots is to use oxalic acid. Thick blotting paper is soaked in a concentrated solution and dried. It is then laid immediately on the blot, and in many instances will take the latter out without leaving a trace behind. In more stubborn cases the cloth is dipped in boiling water and rubbed with crystals of oxalic acid, after which it is soaked in a weak solution of chloride of lime—say 1 ounce to a quart of water. Under such circumstances the linen should be thoroughly rinsed in several waters afterwards. Oxalic acid is undesirable for certain fabrics because it removes the color.

V.—Here is a more harmless method: Equal parts of cream of tartar and citric acid, powdered fine, and mixed together. This forms the “salts of lemon” sold by druggists. Procure a hot dinner plate, lay the part stained in the plate, and moisten with hot water; next rub in the above powder with the bowl of a spoon until the stains disappear; then rinse in clean water and dry.

To Remove Red (Aniline) Ink.
—Stains of red anilines, except eosine, are at once removed by moistening with alcohol of 94 per cent, acidulated with acetic acid. Eosine does not disappear so easily. The amount of acetic acid to be used is ascertained by adding it, drop by drop, to the alcohol, testing the mixture from time to time, until when dropped on the stain, the latter at once disappears.

Cleaning Of Walls, Ceilings, And Wall Paper:

See also Household Formulas.

To Renovate Brick Walls.
—Dissolve glue in water in the proportion of 1 ounce of glue to every gallon of water; add, while hot, a piece of alum the size of a hen’s egg, 1/2 pound Venetian red, and 1 pound Spanish brown. Add more water if too dark; more red and brown if too light.
Cleaning Painted Doors, Walls, Etc.
—The following recipe is designed for painted objects that are much soiled. Simmer gently on the fire, stirring constantly, 30 parts, by weight, of pulverized borax, and 450 parts of brown soap of good quality, cut in small pieces, in 3,000 parts of water. The liquid is applied by means of flannel and rinsed off at once with pure water.
To Remove Aniline Stains From Ceilings, Etc.
—In renewing ceilings, the old aniline color stains are often very annoying, as they penetrate the new coating. Painting over with shellac or oil paint will bring relief, but other drawbacks appear. A very practical remedy is to place a tin vessel on the floor of the room, and to burn a quantity of sulphur in it after the doors and windows of the room have been closed. The sulphur vapors destroy the aniline stains, which disappear entirely.
Old Ceilings.
—In dealing with old ceilings the distemper must be washed off down to the plaster face, all cracks raked out and stopped with putty (plaster of Paris and distemper mixed), and the whole rubbed smooth with pumice stone and water; stained parts should be painted with oil color, and the whole distempered. If old ceilings are in bad condition it is desirable that they should be lined with paper, which should have a coat of weak size before being distempered.
Oil Stains On Wall Paper.
—Make a medium thick paste of pipe clay and water, applying it carefully flat upon the oil stain, but avoiding all friction. The paste is allowed to remain 10 to 12 hours, after which time it is very carefully removed with a soft rag. In many cases a repeated action will be necessary until the purpose desired is fully reached. Finally, however, this will be obtained without blurring or destroying the design of the wall paper, unless it be of the cheapest variety. In the case of a light, delicate paper, the paste should be composed of magnesia and benzine.
To Clean Painted Walls.
—A simple method is to put a little aqua ammonia in moderately warm water, dampen a flannel with it, and gently wipe over the painted surface. No scrubbing is necessary.
Treatment Of Whitewashed Walls.
—It is suggested that whitewashed walls which it is desired to paper, with a view to preventing peeling, should be treated with water, after which the scraper should be vigorously used. If the whitewash has been thoroughly soaked it can easily be removed with the scraper. Care should be taken that every part of the wall is well scraped. {191}
Cleaning Wall Paper.
—I.—To clean wall paper the dust should first be removed by lightly brushing, preferably with a feather duster, and the surface then gently rubbed with slices of moderately stale bread, the discolored surface of the bread being removed from time to time, so as to expose a fresh portion for use. Care should be taken to avoid scratching the paper with the crust of the bread, and the rubbing should be in one direction, the surface being systematically gone over, as in painting, to avoid the production of streaks.

II.—Mix 4 ounces of powdered pumice with 1 quart of flour, and with the aid of water make a stiff dough. Form the dough into rolls 2 inches in diameter and 6 inches long; sew each roll separately in a cotton cloth, then boil for 40 or 50 minutes, so as to render the mass firm. Allow to stand for several hours, remove the crust, and they are ready for use.

III.—Bread will clean paper; but unless it is properly used the job will be a very tedious one. Select a “tin” loaf at least two days old. Cut off the crust at one end, and rub down the paper, commencing at the top. Do not rub the bread backwards and forwards, but in single strokes. When the end gets dirty take a very sharp knife and pare off a thin layer; then proceed as before.

It is well to make sure that the walls are quite dry before using the bread, or it may smear the pattern. If the room is furnished it will, of course, be necessary to place cloths around the room to catch the crumbs.

IV.—A preparation for cleansing wall paper that often proves much more effectual than ordinary bread, especially when the paper is very dirty, is made by mixing 2/3 dough and 1/3 plaster of Paris. This should be made a day before it is needed for use, and should be very gently baked.

If there are any grease spots they should be removed by holding a hot flatiron against a piece of blotting paper placed over them. If this fails, a little fuller’s earth or pipe clay should be made into a paste with water, and this should then be carefully plastered over the grease spots and allowed to remain till quite dry, when it will be found to have absorbed the grease.

V.—Mix together 1 pound each of rye flour and white flour into a dough, which is partially cooked and the crust removed. To this 1 ounce common salt and 1/2 ounce of powdered naphthaline are added, and finally 1 ounce of corn meal, and 1/8 ounce of burnt umber. The composition is formed into a mass, of the proper size to be grasped in the hand, and in use it should be drawn in one direction over the surface to be cleaned.

VI.—Procure a soft, flat sponge, being careful that there are no hard or gritty places in it, then get a bucket of new, clean, dry, wheat bran. Hold the sponge flat side up, and put a handful of bran on it, then quickly turn against the wall, and rub the wall gently and carefully with it; then repeat the operation. Hold a large pan or spread down a drip cloth to catch the bran as it falls, but never use the same bran twice. Still another way is to use Canton flannel in strips a foot wide and about 3 yards long. Roll a strip around a stick 1 inch thick and 10 inches long, so as to have the ends of the stick covered, with the nap of the cloth outside. As the cloth gets soiled, unroll the soiled part and roll it up with the soiled face inside.

In this way one can change places on the cloth when soiled and use the whole face of the cloth. To take out a grease spot requires care. First, take several thicknesses of brown wrapping paper and make a pad, place it against the grease spot, and hold a hot flatiron against it to draw out the grease, which will soak into the brown paper. Be careful to have enough layers of brown paper to keep the iron from scorching or discoloring the wall paper. If the first application does not take out nearly all the grease, repeat with clean brown paper or a blotting pad. Then take an ounce vial of washed sulphuric ether and a soft, fine, clean sponge and sponge the spot carefully until all the grease disappears. Do not wipe the place with the sponge and ether, but dab the sponge carefully against the place. A small quantity of ether is advised, as it is very inflammable.

Clothes And Fabric Cleaners:

Soaps For Clothing And Fabrics.
—When the fabric is washable and the color fast, ordinary soap and water are sufficient for removing grease and the ordinarily attendant dirt; but special soaps are made which may possibly be more effectual.
I.— Powdered borax  30 parts
Extract of soap bark  30 parts
Ox gall (fresh) 120 parts
Castile soap 450 parts

First make the soap-bark extract by boiling the crushed bark in water until it has assumed a dark color, then strain the liquid into an evaporating dish, and {192} by the aid of heat evaporate it to a solid extract; then powder and mix it with the borax and the ox gall. Melt the castile soap by adding a small quantity of water and warming, then add the other ingredients and mix well.

About 100 parts of soap bark make 20 parts of extract.

II.— Castile soap 2 pounds
Potassium carbonate   1/2 pound
Camphor   1/2 ounce
Alcohol   1/2 ounce
Ammonia water   1/2 ounce
Hot water, 1/2 pint, or sufficient.

Dissolve the potassium carbonate in the water, add the soap previously reduced to thin shavings, keep warm over a water bath, stirring occasionally, until dissolved, adding more water if necessary, and finally, when of a consistence to become semisolid on cooling, remove from the fire. When nearly ready to set, stir in the camphor, previously dissolved in the alcohol and the ammonia.

The soap will apparently be quite as efficacious without the camphor and ammonia.

If a paste is desired, a potash soap should be used instead of the castile in the foregoing formula, and a portion or all of the water omitted. Soaps made from potash remain soft, while soda soaps harden on the evaporation of the water which they contain when first made.

A liquid preparation may be obtained, of course, by the addition of sufficient water, and some more alcohol would probably improve it.

Clothes-cleaning Fluids:

See also Household Formulas.

I.— Borax 1 ounce
Castile soap 1 ounce
Sodium carbonate 3 drachms
Ammonia water 5 ounces
Alcohol 4 ounces
Acetone 4 ounces
Hot water to make 4 pints

Dissolve the borax, sodium bicarbonate, and soap in the hot water, mix the acetone and alcohol together, unite the two solutions, and then add the ammonia water. The addition of a couple of ounces of rose water will render it somewhat fragrant.

II.—A strong decoction of soap bark, preserved by the addition of alcohol, forms a good liquid cleanser for fabrics of the more delicate sort.

III.— Chloroform    15 parts
Ether    15 parts
Alcohol   120 parts
Decoction of quillaia bark of 30° 4,500 parts
IV.— Acetic ether    10 parts
Amyl acetate    10 parts
Liquid ammonia    10 parts
Dilute alcohol    70 parts

V.—Another good non-inflammable spot remover consists of equal parts of acetone, ammonia, and diluted alcohol. For use in large quantities carbon tetrachloride is suggested.

VI.— Castile soap  4 av. ounces
Water, boiling 32 fluidounces
Dissolve and add:
Water  1 gallon
Ammonia  8 fluidounces
Ether  2 fluidounces
Alcohol  4 fluidounces
To Remove Spots From Tracing Cloth.
—It is best to use benzine, which is applied by means of a cotton rag. The benzine also takes off lead-pencil marks, but does not attack India and other inks. The places treated with benzine should subsequently be rubbed with a little talcum, otherwise it would not be possible to use the pen on them.
Removal Of Paint From Clothing.
—Before paint becomes “dry” it can be removed from cloth by the liberal application of turpentine or benzine. If the spot is not large, it may be immersed in the liquid; otherwise, a thick, folded, absorbent cloth should be placed under the fabric which has been spotted, and the liquid sponged on freely enough that it may soak through, carrying the greasy matter with it. Some skill in manipulation is requisite to avoid simply spreading the stain and leaving a “ring” to show how far it has extended.

When benzine is used the operator must be careful to apply it only in the absence of light or fire, on account of the extremely inflammable character of the vapor.

Varnish stains, when fresh, are treated in the same way, but the action of the solvent may possibly not be so complete on account of the gum rosins present.

When either paint or varnish has dried, its removal becomes more difficult. In such case soaking in strong ammonia water may answer. An emulsion, formed by shaking together 2 parts of ammonia water and 1 of spirits of turpentine, has been recommended.

To Remove Vaseline Stains From Clothing.
—Moisten the spots with a mixture of 1 part of aniline oil, 1 of {193} powdered soap, and 10 of water. After allowing the cloth to lie for 5 or 10 minutes, wash with water.
To Remove Grease Spots From Plush.
—Place fresh bread rolls in the oven, break them apart as soon as they have become very hot, and rub the spots with the crumbs, continuing the work by using new rolls until all traces of fat have disappeared from the fabric. Purified benzine, which does not alter even the most delicate colors, is also useful for this purpose.
To Remove Iron Rust From Muslin And Linen.
—Wet with lemon juice and salt and expose to the sun. If one application does not remove the spots, a second rarely fails to do so.
Keroclean.
—This non-inflammable cleanser removes grease spots from delicate fabrics without injury, cleans all kinds of jewelry and tableware by removing fats and tarnish, kills moths, insects, and household pests by suffocation and extermination, and cleans ironware by removing rust, brassware by removing grease, copperware by removing verdigris. It is as clear as water and will stand any fire test.
Kerosene. 1 ounce
Carbon tetrachloride (commercial). 3 ounces
Oil of citronella 2 drachms

Mix, and filter if necessary. If a strong odor of carbon bisulphide is detected in the carbon tetrachloride first shake with powdered charcoal and filter.

To Clean Gold And Silver Lace.
—I.—Alkaline liquids sometimes used for cleaning gold lace are unsuitable, for they generally corrode or change the color of the silk. A solution of soap also interferes with certain colors, and should therefore not be employed. Alcohol is an effectual remedy for restoring the luster of gold, and it may be used without any danger to the silk, but where the gold is worn off, and the base metal exposed, it is not so successful in accomplishing its purpose, as by removing the tarnish the base metal becomes more distinguishable from the fine gold.

II.—To clean silver lace take alabaster in very fine powder, lay the lace upon a cloth, and with a soft brush take up some of the powder, and rub both sides with it till it becomes bright and clean, afterwards polish with another brush until all remnants of the powder are removed, and it exhibits a lustrous surface.

III.—Silver laces are put in curdled milk for 24 hours. A piece of Venetian soap, or any other good soap, is scraped and stirred into 2 quarts of rain water. To this a quantity of honey and fresh ox gall is added, and the whole is stirred for some time. If it becomes too thick, more water is added. This mass is allowed to stand for half a day, and the wet laces are painted with it. Wrap a wet cloth around the roller of a mangle, wind the laces over this, put another wet cloth on top, and press, wetting and repeating the application several times. Next, dip the laces in a clear solution of equal parts of sugar and gum arabic, pass them again through the mangle, between two clean pieces of cloth, and hang them up to dry thoroughly, attaching a weight to the lower end.

IV.—Soak gold laces over night in cheap white wine and then proceed as with silver laces. If the gold is worn off, put 771 grains of shellac, 31 grains of dragon’s blood, 31 grains of turmeric in strong alcohol and pour off the ruby-colored fluid. Dip a fine hair pencil in this, paint the pieces to be renewed, and hold a hot flatiron a few inches above them, so that only the laces receive the heat.

V.—Silver embroideries may also be cleaned by dusting them with Vienna lime, and brushing off with a velvet brush.

For gildings the stuff is dipped in a solution of gold chloride, and this is reduced by means of hydrogen in another vessel.

For silvering, one of the following two processes may be employed: (a) Painting with a solution of 1 part of phosphorus in 15 parts bisulphide of carbon and dipping in a solution of nitrate of silver; (b) dipping for 2 hours in a solution of nitrate of silver, mixed with ammonia, then exposing to a current of pure hydrogen.

To Remove Silver Stains From White Fabrics.
—Moisten the fabric for two or three minutes with a solution of 5 parts of bromine and 500 parts of water. Then rinse in clear water. If a yellowish stain remains, immerse in a solution of 150 parts of sodium hyposulphite in 500 parts of water, and again rinse in clear water.
Rust-spot Remover.
—Dissolve potassium bioxalate, 200 parts, in distilled water, 8,800 parts; add glycerine, 1,000 parts, and filter. Moisten the rust or ink spots with this solution; let the linen, etc., lie for 3 hours, rubbing the moistened spots frequently, and then wash well with water. {194}
To Clean Quilts.
—Quilts are cleaned by first washing them in lukewarm soapsuds, then laying them in cold, soft (rain) water over night. The next day they are pressed as dry as possible and hung up; the ends, in which the moisture remains for a long time, must be wrung out from time to time.

It is very essential to beat the drying quilts frequently with a smooth stick or board. This will have the effect of swelling up the wadding, and preventing it from felting. Furthermore, the quilts should be repeatedly turned during the drying from right to left and also from top to bottom. In this manner streaks are avoided.

Removal Of Peruvian-balsam Stains.
—The fabric is spread out, a piece of filter paper being placed beneath the stain, and the latter is then copiously moistened with chloroform, applied by means of a tuft of cotton wool. Rubbing is to be avoided.
Solution For Removing Nitrate Of Silver Spots.—
Bichloride of mercury  5 parts
Ammonium chloride  5 parts
Distilled water 40 parts

Apply the mixture to the spots with a cloth, then rub. This removes, almost instantaneously, even old stains on linen, cotton, or wool. Stains on the skin thus treated become whitish yellow and soon disappear.

Cleaning Tracings.
—Tracing cloth can be very quickly and easily cleaned, and pencil marks removed by the use of benzine, which is applied with a cotton swab. It may be rubbed freely over the tracing without injury to lines drawn in ink, or even in water color, but the pencil marks and dirt will quickly disappear. The benzine evaporates almost immediately, leaving the tracing unharmed. The surface, however, has been softened and must be rubbed down with talc, or some similar substance, before drawing any more ink lines.

The glaze may be restored to tracing cloth after using the eraser by rubbing the roughened surface with a piece of hard wax from an old phonograph cylinder. The surface thus produced is superior to that of the original glaze, as it is absolutely oil- and water-proof.

Rags For Cleaning And Polishing.
—Immerse flannel rags in a solution of 20 parts of dextrine and 30 parts of oxalic acid in 20 parts of logwood decoction; gently wring them out, and sift over them a mixture of finely powdered tripoli and pumice stone. Pile the moist rags one upon another, placing a layer of the powder between each two. Then press, separate, and dry.
Cleaning Powder.—
Bole 500 parts
Magnesium carbonate  50 parts

Mix and make into a paste with a small quantity of benzine or water; apply to stains made by fats or oils on the clothing and when dry remove with a brush.

Cleaning Painted And Varnished Surfaces:

Cleaning And Preserving Polished Woodwork.
—Rub down all the polished work with a very weak alcoholic solution of shellac (1 to 20 or even 1 to 30) and linseed oil, spread on a linen cloth. The rubbing should be firm and hard. Spots on the polished surface, made by alcohol, tinctures, water, etc., should be removed as far as possible and as soon as possible after they are made, by the use of boiled linseed oil. Afterwards they should be rubbed with the shellac and linseed oil solution on a soft linen rag. If the spots are due to acids go over them with a little dilute ammonia water. Ink spots may be removed with dilute or (if necessary) concentrated hydrochloric acid, following its use with dilute ammonia water. In extreme cases it may be necessary to use the scraper or sandpaper, or both.

Oak as a general thing is not polished, but has a matt surface which can be washed with water and soap. First all stains and spots should be gone over with a sponge or a soft brush and very weak ammonia water. The carved work should be freed of dust, etc., by the use of a stiff brush, and finally washed with dilute ammonia water. When dry it should be gone over very thinly and evenly with brunoline applied with a soft pencil. If it is desired to give an especially handsome finish, after the surface is entirely dry, give it a preliminary coat of brunoline and follow this on the day after with a second. Brunoline may be purchased of any dealer in paints. To make it, put 70 parts of linseed oil in a very capacious vessel (on account of the foam that ensues) and add to it 20 parts of powdered litharge, 20 parts of powdered minium, and 10 parts of lead acetate, also powdered. Boil until the oil is completely oxidized, stirring constantly. When completely oxidized the oil is no longer red, but is of a dark brown color. When it acquires {195} this color, remove from the fire, and add 160 parts of turpentine oil, and stir well. This brunoline serves splendidly for polishing furniture or other polished wood.

To Clean Lacquered Goods.
—Papier-maché and lacquered goods may be cleaned perfectly by rubbing thoroughly with a paste made of wheat flour and olive oil. Apply with a bit of soft flannel or old linen, rubbing hard; wipe off and polish by rubbing with an old silk handkerchief.
Polish For Varnished Work.
—To renovate varnished work make a polish of 1 quart good vinegar, 2 ounces butter of antimony, 2 ounces alcohol, and 1 quart oil. Shake well before using.
To Clean Paintings.
—To clean an oil painting, take it out of its frame, lay a piece of cloth moistened with rain water on it, and leave it for a while to take up the dirt from the picture. Several applications may be required to secure a perfect result. Then wipe the picture very gently with a tuft of cotton wool damped with absolutely pure linseed oil. Gold frames may be cleaned with a freshly cut onion; they should be wiped with a soft sponge wet with rain water a few hours after the application of the onion, and finally wiped with a soft rag.
Removing And Preventing Match Marks.
—The unsightly marks made on a painted surface by striking matches on it can sometimes be removed by scrubbing with soapsuds and a stiff brush. To prevent match marks dip a bit of flannel in alboline (liquid vaseline), and with it go over the surface, rubbing it hard. A second rubbing with a dry bit of flannel completes the job. A man may “strike” a match there all day, and neither get a light nor make a mark.

Stone Cleaning:

Cleaning And Polishing Marble.
—I.—Marble that has become dirty by ordinary use or exposure may be cleaned by a simple bath of soap and water.

If this does not remove stains, a weak solution of oxalic acid should be applied with a sponge or rag, washing quickly and thoroughly with water to minimize injury to the surface.

Rubbing well after this with chalk moistened with water will, in a measure, restore the luster. Another method of finishing is to apply a solution of white wax in turpentine (about 1 in 10), rubbing thoroughly with a piece of flannel or soft leather.

If the marble has been much exposed, so that its luster has been seriously impaired, it may be necessary to repolish it in a more thorough manner. This may be accomplished by rubbing it first with sand, beginning with a moderately coarse-grained article and changing this twice for finer kinds, after which tripoli or pumice is used. The final polish is given by the so-called putty powder. A plate of iron is generally used in applying the coarse sand; with the fine sand a leaden plate is used; and the pumice is employed in the form of a smooth-surfaced piece of convenient size. For the final polishing coarse linen or bagging is used, wedged tightly into an iron planing tool. During all these applications water is allowed to trickle over the face of the stone.

The putty powder referred to is binoxide of tin, obtained by treating metallic tin with nitric acid, which converts the metal into hydrated metastannic acid. This, when heated, becomes anhydrous. In this condition it is known as putty powder. In practice putty powder is mixed with alum, sulphur, and other substances, the mixture used being dependent upon the nature of the stone to be polished.

According to Warwick, colored marble should not be treated with soap and water, but only with the solution of beeswax above mentioned.

II.—Take 2 parts of sodium bicarbonate, 1 part of powdered pumice stone, and 1 part of finely pulverized chalk. Pass through a fine sieve to screen out all particles capable of scratching the marble, and add sufficient water to form a pasty mass. Rub the marble with it vigorously, and end the cleaning with soap and water.

III.— Ox gall  1 part
Saturated solution of sodium carbonate  4 parts
Oil of turpentine  1 part
Pipe clay enough to form a paste.
IV.— Sodium carbonate  2 ounces
Chlorinated lime.  1 ounce
Water 14 ounces

Mix well and apply the magma to the marble with a cloth, rubbing well in, and finally rubbing dry. It may be necessary to repeat this operation.

V.—Wash the surface with a mixture of finely powdered pumice stone and vinegar, and leave it for several hours; then brush it hard and wash it clean. When dry, rub with whiting and wash leather.

VI.— Soft soap. 4 parts
Whiting 4 parts
Sodium bicarbonate 1 part
Copper sulphate 2 parts

Mix thoroughly and rub over the marble with a piece of flannel, and leave it on for 24 hours, then wash it off with clean water, and polish the marble with a piece of flannel or an old piece of felt.

VII.—A strong solution of oxalic acid effectually takes out ink stains. In handling it the poisonous nature of this acid should not be forgotten.

VIII.—Iron mold or ink spots may be taken out in the following manner: Take 1/2 ounce of butter of antimony and 1 ounce of oxalic acid and dissolve them in 1 pint of rain water; add enough flour to bring the mixture to a proper consistency. Lay it evenly on the stained part with a brush, and, after it has remained for a few days, wash it off and repeat the process if the stain is not wholly removed.

IX.—To remove oil stains apply common clay saturated with benzine. If the grease has remained in long the polish will be injured, but the stain will be removed.

X.—The following method for removing rust from iron depends upon the solubility of the sulphide of iron in a solution of cyanide of potassium. Clay is made into a thin paste with ammonium sulphide, and the rust spot smeared with the mixture, care being taken that the spot is only just covered. After ten minutes this paste is washed off and replaced by one consisting of white bole mixed with a solution of potassium cyanide (1 to 4), which is in its turn {197} washed off after about 2 1/2 hours. Should a reddish spot remain after washing off the first paste, a second layer may be applied for about 5 minutes.

XI.— Soft soap 4 ounces
Whiting 4 ounces
Sodium carbonate 1 ounce
Water, a sufficient quantity.

Make into a thin paste, apply on the soiled surface, and wash off after 24 hours.

XII.—In a spacious tub place a tall vessel upside down. On this set the article to be cleaned so that it will not stand in the water, which would loosen the cemented parts. Into this tub pour a few inches of cold water—hot water renders marble dull—take a soft brush and a piece of Venetian soap, dip the former in the water and rub on the latter carefully, brushing off the article from top to bottom. When in this manner dust and dirt have been dissolved, wash off all soap particles by means of a watering pot and cold water, dab the object with a clean sponge, which absorbs the moisture, place it upon a cloth and carefully dry with a very clean, soft cloth, rubbing gently. This treatment will restore the former gloss to the marble.

XIII.—Mix and shake thoroughly in a bottle equal quantities of sulphuric acid and lemon juice. Moisten the spots and rub them lightly with a linen cloth and they will disappear.

XIV.—Ink spots are treated with acid oxalate of potassium; blood stains by brushing with alabaster dust and distilled water, then bleaching with chlorine solution. Alizarine ink and aniline ink spots can be moderated by laying on rags saturated with Javelle water, chlorine water, or chloride of lime paste. Old oil stains can only be effaced by placing the whole piece of marble for hours in benzine. Fresh oil or grease spots are obliterated by repeated applications of a little damp, white clay and subsequent brushing with soap water or weak soda solution. For many other spots an application of benzine and magnesia is useful.

XV.—Marble slabs keep well and do not lose their fresh color if they are cleaned with hot water only, without the addition of soap, which is injurious to the color. Care must be taken that no liquid dries on the marble. If spots of wine, coffee, beer, etc., have already appeared, they are cleaned with diluted spirit of sal ammoniac, highly diluted oxalic acid, Javelle water, ox gall, or, take a quantity of newly slaked lime, mix it with water into a paste-like consistency, apply the paste uniformly on the spot with a brush, and leave the coating alone for two to three days before it is washed off. If the spots are not removed by a single application, repeat the latter. In using Javelle water 1 or 2 drops should be carefully poured on each spot, rinsing off with water.

To Remove Grease Spots From Marble.
—If the spots are fresh, rub them over with a piece of cloth that has been dipped into pulverized china clay, repeating the operation several times, and then brush with soap and water. When the spots are old brush with distilled water and finest French plaster energetically, then bleach with chloride of lime that is put on a piece of white cloth. If the piece of marble is small enough to permit it, soak it for a few hours in refined benzine.
Preparation For Cleaning Marble, Furniture, And Metals, Especially Copper.
—This preparation is claimed to give very quickly perfect brilliancy, persisting without soiling either the hand or the articles, and without leaving any odor of copper. The following is the composition for 100 parts of the product: Wax, 2.4 parts; oil of turpentine, 9.4 parts; acetic acid, 42 parts; citric acid, 42 parts; white soap, 42 parts.
Removing Oil Stains From Marble.
—Saturate fuller’s earth with a solution of equal parts of soap liniment, ammonia, and water; apply to the greasy part of the marble; keep there for some hours, pressed down with a smoothing iron sufficiently hot to warm the mass, and as it evaporates occasionally renew the solution. When wiped off dry the stain will have nearly disappeared. Some days later, when more oil works toward the surface repeat the operation. A few such treatments should suffice.
Cleaning Terra Cotta.
—After having carefully removed all dust, paint the terra cotta, by means of a brush, with a mixture of slightly gummed water and finely powdered terra cotta.
