Product Review; "For more than just musical instruments - Herco Products (Manufactured by Dunlop) do a great job restoring any tarnished brass, bronze silver (and more) to their original shine. You can find / request Herco Cleaning Cloths at your local music store, but they're available online and quite affordable. One cloth will last for many uses, whether you play trumpet, guitar or just want to clean up some old household items / tools."
