A specially formulated composition is provided for the cleaning and polishing of cymbals. The formulation, which is an aqueous suspension, can be applied as a spray from an aerosol can. The composition not only removes dirt and provides a glossy shine, but retards subsequent tarnishing of the brass cymbal. The active ingredients of the composition include kaolin clay, thioglycolic acid or its ammonium salt, an anionic surfactant, and water.
