Usage:Drainage of basins, vegetable sinks, floor drains (kitchen, shower rooms, etc.)Need to clear the accumulated water inside and outside the pipeline mouth; If there is a hose, please unplug the interface and use it directly on the main pipeline. If it cannot be disassembled, it is recommended to reduce the usage and use this product in small quantities multiple times.Pour about 50g of this product each time (about 2 caps are flush with each other) directly into the pipeline (pour in the second cap every 13 minutes). After 12 minutes, rinse with warm water (hot water is recommended for severe oil blockage, which can greatly improve the reaction and dissolution ability of the dredging agent). When pouring warm water, be sure to maintain a safe distance of more than 60cm.Wait for 10 minutes to observe if there is still a reaction. If no hot water is poured, wait for 60 minutes. If the blockage still persists, repeat the above steps.Toilet and squatting pit dredgingBefore use, try to remove any accumulated water in the toilet that exceeds the normal water level.Pour 100 grams of unclogging agent (about 4 bottle caps flush with the lid) into the toilet bowl each time, and add an appropriate amount of hot water (for severe oil blockage, it is recommended to use hot water above 50 degrees Celsius, which can greatly improve the reaction and dissolution ability of the unclogging agent).Wait for 10 minutes to observe if there is still a reaction. If no more hot water is poured, wait for 1 hour. If the blockage is still not cleared, repeat the operation and use it with a skin clip (sometimes the blockage has already dissolved, just a little external force is needed to clear it).Instructions for using the main pipelineRemove the accumulated water inside and outside the pipeline opening.Pour 100 grams of this product into the pipeline each time (about 4 bottle caps are flush with the lid), add an appropriate amount of hot water, and wait for the reaction to dissolve (for severe oil blockage, it is recommended to use hot water above 50 degrees Celsius, which can greatly improve the reaction dissolution ability of the dredging agent). After waiting for 12 hours, test the dredging effect with plenty of water. If the dredging is still not done, repeat the operation.Maintenance and deodorization (antibacterial, odor removal)Pour about 50g of this product each time (about 2 caps flush) into a tube, add clean water, and rinse after 10 minutes.
