Ultrasonic cleaning is fine for expensive coins with very little dirt on them. It hardly leaves an impression on coins covered in mud, grime or oxides. I would consider it as a luxury treatment and wonder why take the risk, is this is about very little dirt anyway?

An unidentified coin is a piece of metal. An identified coin is a piece of history.
