Water, 1 gallon,

Cyanid of potassium (fused), 1 pound.

This preparation is used by a noted firm of silverware manufacturers. The same proportions made in smaller quantities will be of great use, as the cleaning fluid may be kept and used any number of times.

Dip the silver and leave it entirely covered for 4 or 5 minutes, then wash off with cold water, then with hot water, soap and sponge, then with cold water again, wipe dry, with a soft cloth, and polish with chamois and jeweler's rouge.
