Method 2: Dismantle the pipeline and clean it. This method is more thorough and convenient to clean, but it is more difficult. In order to ensure the cleaning quality, it is necessary to calculate the disassembly distance accurately.
Method 3: In the oil fume pipeline which is inaccessible to human and difficult to disassemble, we can use the method of opening holes, drill some small holes in the oil fume pipeline, clean the inside of the pipeline through the small holes, and then seal each small hole.
Method 4: Soft brush-assisted cleaning method: spray some cleaning agent in the oil fume pipeline to soften the oil stain, and then stick the cleaning agent with a long electric soft shaft brush to clean the oil stain. This method is generally used for inaccessible and inconvenient disassembly of short vertical range hood pipes and concealed small pipes. This cleaning method is easy to accumulate oil, so the cleaning cycle should be shortened.
Method 5: Use professional cleaning equipment to clean the kitchen oil fume pipeline. With the continuous development and progress of science and technology, professional oil fume pipeline cleaning equipment appears on the market, which is similar to cleaning robot, but the price and cost may be relatively high. Conditional friends can choose this cleaning equipment.
Method 6: This method is mainly used to clean the vertical flue over 50 cm, because technicians need to remove the top and bottom of the pipeline, fix the overhead safety rope above the flue and fasten the safety belt, and then clean the oil in the vertical flue from top to bottom. This method is very dangerous, highly technical and expensive, but its cleaning effect is very good, because the vertical flue generally has less oil accumulation, so it can be cleaned once a year.
