To Clean Brass and Copper

April 23rd, 2017

Scrape a little rotten-stone fine, and make into a paste with sweet oil. Rub on with a piece of flannel; let it dry, and polish with a chamois-skin. Copper is cleaned either with vinegar and salt mixed in equal parts, or with oxalic acid. The latter is a deadly poison, and must be treated accordingly.
