Dissolve 6 lb. soap in 8 gal. boiling water; and in another vessel dissolve 3 lb. best pearlash in 2 gal. boiling water. First clean the curtains, one at a time, in two lots of clean water, well working them in each water; then fold them up smoothly, and put each curtain on a peg by itself to drain. Put 6 pails warm water into a tub, and into this put 2 qt. of the pearlash liquor and 2 gal. of the soap liquor. Put one of the curtains into this liquor, and well work it with the puncher for 10 minutes, then fold it up and put it on a peg to drain, and treat the other curtain exactly in the same manner. Now throw this liquor away, and make up a second lot with the same proportions as the first. Pass the curtains through this in the same manner as before, letting the one which was second be first this time. Put this liquor into another vessel and make up a third lot, and well work the curtains in this as before. Empty this liquor into the vessel containing the last, and mix another lot. Punch the curtains in this as before, one at a time, for 10 minutes, fold up and put on the pegs to drain, and they are ready for spiriting. Rinse your tub and put into it 12 pails of cold water, and into this stir 1/2 pint of oil of vitriol.
Open your first curtain and well handle it in this spirit water for 10 minutes, then fold and hang up to drain. Stir another 1/4 pint of oil of vitriol into this same water, and treat the second curtain in the same manner as the first. Now throw this spirit water away, well rinse the tub, and fill it with cold water. Rinse the first curtain in this, then throw away the water, refill the tub, and rinse the second curtain. Fold them up smoothly, drain them, and they are ready for drying. To dry these curtains properly they must be hung up in a warm room by the ends, the middle hanging down. This is of great importance and must be attended to, for if they are not dried straight they cannot be re-made straight, and consequently will not hang again like new. After drying they are to be well shaken and picked out, and then sent to the pressers to be finished. The proportions aud quantities heregiven are for a pair of curtains, each containing 20 sq. yd.
Worsted-and-Cotton Damasks are to be cleaned exactly in the manner described above, excepting that after being spirited and rinsed, and before being pressed, they must have a water starch to make them look strong and well when finished.
Dissolve 2 lb. Feild's soft-soap in 2 gal. boiling water, and while it is getting cold get ready your silk-scouring brushes and scouring board. Have 3 vessels, each containing 6 pails of cold water for rinsing, and a fourth, containing the same quantity of water, into which sufficient oil of vitriol has been stirred to make it taste sour; also a kettle, containing. 4 pails of water for a soap liquor. Put 1 qt. of the soft-soap liquor into a pail of cold water, dip one width of the damask into this, then put it on the scouring board, the wrong side up, pour some of the dissolved soap on it, and well brush with the silk-scouring brush. This must not occupy more than 5 minutes. Turn it and clean the right side quickly with the brush and more of the soft-soap. Now take it off the board and pass it through the first soap liquor, then through the thin liquor, the rinsing waters, and the spirit water; well handling it in the spirits for 2 minutes. Wring it, fold it up, and dry; and so proceed for each width, the quantities here given being sufficient to clean about 10 sq. yd.
After drying, they must be damped, brushed, and framed, and sent to the pressers to be finished.
Silk damasks may also be cleaned with camphine, in the following manner: Well shake and brush the curtains, and take the widths apart. Have ready the camphine board, brushes, and sheets. Put 1 gal. camphine into an earthenware pan that will hold 4 gal. Put in a width of the damask, and handle it in the camphine until it is well soaked, which will be in about 2 minutes; then fold it up and lay it on a peg over the pan, so as to catch the liquor which drains from it. Now put it on the 2 scouring board, wrong side up, and brush it well; then turn up the right side, and do the same with it. Pass it again through the camphine, fold it up, squeeze out of it as much of the camphine as possible, and lay it on the peg over the pan. Now turn your board the wood side upwards, and put your sheets on it. Then sheet-up the width which you have just cleaned, using one sheet after the other until it is quite dry; then brush it well on both sides, and hang it up to air and take off the smell of the camphine. Each width of the curtain or furniture is to be treated in exactly the same manner as above.
When dry they are ready for dressing.
Mix 1 teacupful of parchment size with 4 qt. cold water. Frame the damask, and carefully wet all over with this by means of a clean sponge, and dry immediately with the charcoal fire. Afterwards send them to the pressers to be finished. Some dyers and cleaners prefer damping, brushing, and calendering as a finish for this work; while others frame or roll it only. But this will all depend on the quality of the work and the dressing.
Rapidity of operation is of great importance in this method, for if the operator be a dawdler the work is sure to suffer. Each width, from the time it is put into the camphine until it is hung up to air, should not on any account take more than 15 minutes.
To clean a curtain, or other furniture containing about 10 sq. yd. Dissolve 3 lb. soap in 8 gal. boiling water; have ready 3 tubs, each containing 6 pails cold water, and into the first and second put 1 pail of the dissolved soap, and 1/2 pail into the third. Put into a large kettle, or other vessel, 6 pails cold water, and well stir into it 1/4 teacup of oil of vitriol.
Put the curtain into the first soap liquor, and well work it for 1 minute, then take it up by the selvage and wring it over the tub; put it back into the same liquor and again well work it for a minute, and then well wring it on a peg over the tub. Now treat it in the same manner in the second liquor, then put it into the third or thin soap liquor, and when it has been well worked in this, handle it directly out of the soap into the spiriting, wring it out on a peg, put it back into the spirits, and again well handle it for about a minute, and then put it to drain. Throw away the first soap liquor, rinse the tub, and put into it 10 pails of cold water and 1/2 teacup of oil of vitriol. Well handle the curtain in this, wring it out, return it twice to the same liquor, and then hang it on to the pegs to drain. Empty your tub and make up a second spirit water, with 1/4 teacup of oil of vitriol in 12 pails of water, well work the curtain in this, and afterwards put it to drain. After it has drained well, dry it with clean sheets, and then hang it in a warm room to finish drying. When dry, damp, brush, and send to the pressers to be finished. The sheeting-up should be carefully performed, and must on no account be omitted, as the whole safety of the colours depends on this operation.
