1. The kitchen smoke exhaust system where the range hood is cleaned is relatively large. Cleaning the hood requires professional technicians to enter the flue. First, a large amount of oil in the flue is removed with special tools and efficient oil agent, then the oil agent is sprayed with a high-pressure cleaning machine, and then washed with clean water. For some small pipes that technicians can't enter the pipeline, many professionals will use mechanical equipment to clean the pipe opening. It should be noted here that after the opening operation, it should be closed in time. Otherwise there will be loopholes and other phenomena.
2. If the fan is cleaned for a long time, the blades on the fan will form heavy oil stains, which will also affect the exhaust effect of the fan. When cleaning, first remove the fan and clean the internal impeller, inner wall and surface. It is suggested to add lubricating oil to the fan after cleaning and before assembly to make the fan more flexible.
3. Cleaning the fume purifier will also be affected by the ventilation effect of the kitchen smoke exhaust system. After long-term use, there is a lot of oil pollution on the internal electrode plate and filter screen, and the purification effect becomes worse. When cleaning, it is recommended to soak and clean with efficient cleaning agent first.
