It is supposed that an article composed of lacquered brass and copper requires to be cleaned, burnished, and re-lacquered. First remove the lacquer by brushing with an ordinary scrubbing-brush and strong boiling soda water. Then wash off with hot water, and polish with flour emery powder, crocus, and oil. Finish with dry crocus or very fine whiting. A calico dolly may be fixed to a lathe and the polishing done more easily. To lacquer, the articles must be heated equally.
