Black Lace.
½ cup rain water, or very soft spring water.
1 teaspoonful borax.
1 tablespoonful spirits of wine.
Squeeze the tumbled rusty lace through this four times, then rinse in a cup of hot water in which a black kid glove has been boiled. Pull out the edges of the lace until almost dry; then press for two days between the leaves of a heavy book.
