Best Practices for Use

When using an ultrasonic cleaner, ensure that parts are suspended or placed in a tray rather than resting directly on the tank bottom to allow efficient cavitation and protect both parts and tank. After cleaning, rinse items with fresh water to remove residual solution and dry thoroughly before further handling. Ultrasonic cleaning systems like the M2800 should always be operated with appropriate cleaning solutions and safety precautions to avoid chemical or thermal injury.
