The Ultrasonic Cleaning System is the newest and best method for cleaning available today. It is used for everything from jewelry to car parts. In the music industry, they have become the standard to which everything else is compared. Musical instrument manufacturers around the world are using this process in their assembly and lacquering of instruments. Many music stores across the country have begun to use this system for cleaning high end, and especially silver instruments. Amend Music Center is one of very few stores in the state of Washington that has this equipment available in store. We have been using this system for over 10 years.
