All wool goods require the greatest care in washing. The different waters used should be of the same temperature, and never too hot to be borne comfortably by the hands. Soap should always be used in the form of a solution. No soap should be rubbed on the fabric, and only a good white soap, free from resin, or a soft potash soap is allowable. Make each water slightly soapy, and leave a very little in the fabric at the last rinsing, in order to furnish a dressing as nearly like the original as possible. Ammonia or borax is sometimes used in preference to soap. For pure white flannel borax is the most satisfactory, on account of its bleaching quality. Only enough of any alkali should be used to make the water very soft.
Wool fibres collect much dust, and should therefore be thoroughly brushed or shaken before the fabric is put into the water. Woollen fabrics should be cleansed by squeezing, and not by rubbing. Wool should not be wrung by hand. Either run the fabric smoothly through a wringer or squeeze the water out, so that the fibres may not become twisted. Woollen articles may be dried more quickly by rolling the article tightly in a thick, dry towel or sheet, and squeezing the whole till all moisture is absorbed. Shake the article thoroughly before placing to dry. Woollen goods should not be allowed to freeze, for the teeth become knotted and hard.
