To clean a bronze chandelier that is corroded by damp, take the chandelier to pieces and carefully remove all pins, screws, and other iron parts. Then place about 1/2 lb. of potash in l gal. of water, and in this boil off all the old lacquer. Allow the various parts to remain in the solution for about twenty-five minutes; then take them out and well wash in clean cold water. They should then be dipped in aquafortis, and allowed to remain sufficiently long to become bright. Each part should be held in the acid bath by means of a copper wire twisted round, or by holding with a small pair of brass tongs. Then well rinse in several changes of clean cold water, either by having several vessels or by well rinsing in running water. Transfer to the sawdust tub, dry, and relacquer.
