1. Take photos of the areas to be cleaned before the cleaning process.
2. Manually remove grease deposits from the flue with a shovel. If the intake cannot be accessed, use a cutting device to open it first, then enter and clear the grease. Pipes between those less than 0.3 meters will be cleaned without leaving any blind spots.
After removing oil stains, use a cleaning machine to distribute oil to the spray cleaning area to remove the stains.
Clean with clean water for cleaning and sanitization.
Thoroughly clean all parts by hand, ensuring no uncleaned areas remain.
Ensure any openings are sealed to prevent any air leaks.
Inspect the cleaning area, take photos for customer comparison before and after, and save the files for storage.
If the flue size is too small (less than 40 cm) and cannot be accessed manually, this method should be used. Cleaners will move a section of the flue away from the site according to the actual conditions and clean it on both sides. This method offers good cleaning results but is difficult and expensive.
For parallel flues, the cleaner can bore (over 40 cm) and manually clean. This method is labor-intensive and yields good cleaning results. However, it is important to enhance ventilation and equip with low-voltage (36V) lighting power.
Method of Operation: Some flues cannot be manually disassembled. This method can be used. Cleaning personnel should use special spark-free hole tools to open one or more holes in the ventilation pipe, with the size, spacing, and number of openings based on the on-site conditions. After opening the holes, perform manual cleaning. Once cleaned, seal and restore the pipe.
