Wash well in strong, warm soap-suds, rinse and wipe dry with a dry
soft cloth; then mix as much hartshorn powder as will be required into
a thick paste, with cold water; spread this over the silver, with a
soft cloth, and leave it for a little time to dry. When perfectly dry
brush it off with a clean soft cloth, or brush and polish it with a
piece of chamois skin. Hartshorn is one of the best possible
ingredients for plate powder for daily use. It leaves on the silver a
deep, dark polish, and at the same time does not injure it. Whiting,
dampened with liquid ammonia, is excellent also.
