Cleaning Tarnished Silverware.
[IN USE BY ALL LEADING JEWELERS.]
| Cyanide potassium3 | ounces. |
| Soft water2 | gallons. |
Mix and dissolve. Label it “poison,” and place out of the reach of children. Have the article clean and free from grease; dip in solution till tarnish is off, but no longer (and under no circumstances leave it in too long). After immersion the article must be taken out and thoroughly rinsed in a number of waters (warm preferred), then dried with a soft rag or sawdust.
Another method, which is safe and cheap, consists in using a saturated solution of hyposulphite of soda to which a little bolted whiting has been added. Apply with a brush or cloth until the tarnish is removed.
