Our Small Silver Polishing Cloth is a soft microfibre pre-treated with fine silver polishing compound. Use a gentle pressure to wipe away tarnish and follow with a light buffing with a soft clean cloth to bring your silver instrument or mouthpiece to a mirror finish. If you polish your mouthpiece with the silver polishing cloth, please wash the mouthpiece with soapy water before playing.Each small silver polishing cloth is about 6 inches square (15cm) and will be effective as long as it is not washed (washing will remove the polishing compound from the cloth). Wash your hands after using.
