Using an IV drip is effective for cleaning carbon deposits. There are two main methods for removing carbon buildup in a car: 1. IV drip cleaning: A bottle tool is suspended above the engine, and a cleaning agent is poured into it. The agent is then introduced into the engine through a tube to clean the carbon deposits. However, if the engine has severe carbon buildup, this method may clog or damage the catalytic converter system. 2. Machine cleaning: The cleaning agent is injected into a machine, which pressurizes and sprays it into the combustion chamber. The agent reacts with and dissolves the carbon deposits, and the waste liquid is then extracted. This method is more effective for severe carbon buildup and does not require engine disassembly, but it is more expensive, and the engine oil needs to be replaced after cleaning.

I've been driving for nearly twenty years and have accumulated quite a bit of car repair experience. Using an IV drip to clean carbon deposits does have some effect, especially for mild carbon buildup—like when the engine idles roughly or lacks power during acceleration. Cleaning might show immediate results in such cases. It works by injecting a cleaning agent to dissolve surface dirt, and it's inexpensive and quick to perform. However, the downsides are obvious: deep carbon deposits may not be thoroughly cleaned, leading to no long-term improvement or even wasted money. If the cleaning agent flows into other components, it could clog pipes or damage sensors. My personal advice is to try a simple cleaning first to see the results; if that doesn’t work, opt for disassembly and deeper treatment. Prevention is even more important—regularly changing to high-quality oil and driving more on highways can reduce carbon buildup. After all, a healthy engine makes for a smoother and more enjoyable drive.

As an ordinary car owner, I tried carbon deposit cleaning with fuel injector cleaner last year. At that time, the engine was shaking severely, and after the cleaning, the shaking reduced somewhat, and fuel consumption also decreased a bit, so it felt somewhat effective. However, upon checking the information, I found that this is just superficial work, and the deeper issues remain unresolved; it won't last long before the problem recurs. Now, thinking back, it might be better to go directly to the 4S shop for a disassembly cleaning, which is more reliable. In terms of cost, spending one or two hundred yuan on fuel injector cleaner isn't expensive, but the effect isn't lasting. Don't count on it to save the day when carbon deposits are severe. Safe driving habits and using high-quality gasoline are the key—they save both worry and money.

I've been into car modifications for several years, and using fuel system cleaners for carbon deposits works quite well for mild issues, especially for direct injection engines prone to carbon buildup. After injecting the cleaner, it can quickly dissolve some carbon deposits and restore engine power. But don't expect too much—it's completely ineffective for serious issues like piston sticking or exhaust blockage. Prevention is always the best strategy. Using synthetic oil and avoiding short trips can reduce carbon deposit formation. Remember, spending a little on cleaning is not as good as developing good habits from the source.
