We possess unique cleaning technology. Before cleaning, professional grease detection instruments are used to accurately determine the degree and distribution of grease buildup. During the disassembly process, technicians leverage their skilled techniques to quickly and damage-free separate various components of the range hood. Different cleaning methods are applied based on the components: for heavily greased fan wheels, ultrasonic cleaning technology is employed, using high-frequency vibrations to rapidly remove grease; for exterior surfaces and other parts, high-pressure steam cleaning is utilized, which not only efficiently removes dirt but also sterilizes and disinfects. After cleaning, key components are lubricated to extend the lifespan of the range hood.
