What are the steps for performing an automotive fuel system cleaning (commonly known as 'IV drip cleaning')?

Steps for automotive fuel system cleaning (IV drip cleaning): 1. Open the hood, remove the vehicle's fuel pump fuse, and add ultra-concentrated fuel injector cleaner to the no-disassembly fuel system cleaning equipment; 2. Add the cleaning solution and hang the pressurized equipment on the vehicle's front hood; 3. Place a cloth beneath the fuel line, slowly disconnect the fuel inlet pipe, connect it to the equipment's fuel line, and start the engine of the vehicle being cleaned after confirming everything is correct. IV drip cleaning is now a very common maintenance method, primarily used for cleaning the engine's intake tract and fuel system. The advantages of this method include convenience and speed, as it can thoroughly clean the engine without disassembly, achieving excellent results.
In my daily routine of car maintenance, performing an engine carbon cleaning with a drip bottle is a common procedure. The steps are generally as follows: First, ensure the vehicle is in a safe condition, such as being parked with the engine off and the handbrake engaged, to prevent any movement that could cause danger. Then, prepare the drip bottle equipment, including the cleaning agent, input tube, and bottle, checking for proper sealing to avoid leaks. Next, connect the equipment to the engine's intake system interface, such as the throttle position, ensuring the pipes are secure to prevent detachment. Start the engine and let it idle at around 800 RPM, then slowly inject the cleaning agent, controlling the flow rate to about a small segment per minute, avoiding too fast a flow to prevent damage to internal components. The entire process lasts 10-15 minutes, during which observe any changes in the engine. After completion, turn off the engine, remove the equipment, clean up the area, and run the vehicle for a few minutes to expel exhaust gases. I recommend checking monthly or based on mileage to maintain engine efficiency and reduce emissions, but if you're not familiar with the process, it's best to have it done by a professional shop.
Last time I went to the 4S shop for maintenance, the technician performed an engine carbon cleaning with a hanging bottle for me. The steps were quite simple to describe. After parking and turning off the car, they hung a specialized small bottle and connected a hose to the car's air intake. The engine was started and kept idling in place, then the cleaning fluid was slowly poured into the bottle and flowed through the hose. The technician explained while operating that the cleaner would decompose carbon deposits and improve performance, and the whole process took about ten minutes. After removing the equipment, they also asked me to drive around for a few minutes to expel any residues. The effect was quite obvious—I could feel the throttle was smoother and acceleration was faster. Doing it yourself carries significant risks; if the connection is wrong or the liquid flows too fast, it might damage the engine. It's recommended to do this cleaning regularly every 10,000 to 20,000 kilometers to maintain cleanliness.
As a car enthusiast, I often perform intake system cleaning with emphasis on details and safety. Steps: Park the car and turn off the engine, check if the engine is cool. Hang the cleaning bottle and connect it to the intake system port. Start the engine at idle speed, slowly inject cleaner while controlling the flow rate, run for 10 minutes to allow carbon deposits to decompose. After completion, turn off the engine and clean the equipment, then drive the vehicle to exhaust. Precautions include using certified cleaners to avoid corrosion, and ensuring proper ventilation to prevent poisoning.
