Open the cover and add water (fill the sink with more than 2/3) 2. Add the corresponding cleaning detergent (add according to the product) 3. Mix the cleaning detergent well 4. Put in cleaning objects (it is best to soak them before cleaning) 5. Set the time and temperature according to the product requirements (only for the non-heating type) 6. Disconnect the power after washing, drain the sewage, and clean and maintain the tank with a dry cloth.Cleaning Principle: The principle of the ultrasonic cleaning machine is mainly to convert the sound energy of a power ultrasonic frequency source into mechanical vibration through a transducer, and to radiate ultrasonic waves to the cleaning liquid in the tank by cleaning the tank wall. Due to the radiation of ultrasonic waves, the micro-bubbles in the liquid in the tank can be kept under vibration by the sound wave. The adsorption of the dirt on the surface of the cleaning member is destroyed, which causes the fatigue layer of the dirt layer to be separated, and the vibration of the gas bubbles scrubs the solid surface..
