Put one pound of washing crystals into an enameled utensil and pour one quart of boiling water over them. In another utensil or earthenware bowl mix one-half pound of chloride of lime and two quarts of cold water. Then combine the two solutions and let stand to settle. Pour off the clear liquid, straining through several thicknesses of cheese cloth. Bottle in dark colored bottles and keep tightly corked. If solution takes on a pink tinge its effectiveness is not reduced. Use on white cotton or linen only as it removes color and injures wool and silk.
