The new RCBS® Ultrasonic Case Cleaner-2 includes significant changes from the previous model. The Ultrasonic Case Cleaner-2 is larger – nearly 100 percent larger. The 6.3-quart capacity is twice as big, with a second ceramic heater and transducer to better clean brass cases and firearm parts. The LED is easily programmable, and the timer can be set for up to 30 minutes of continuous cleaning. The Ultrasonic Case Cleaner-2 delivers clean brass in a short amount of time.
