What is the most effective method to clean carbon deposits?

Here are the methods to deal with carbon deposits in cars: 1. Engine disassembly and cleaning is the most effective way to remove carbon deposits, but the entire process requires a significant amount of time and effort. The engine needs to be disassembled, and cleaning agents, ultrasonic methods, etc., are used to completely and thoroughly remove carbon deposits from the components. 2. Using an IV drip method for the car, where a tool is suspended above the engine, and cleaning agents are poured into the tool and introduced into the engine through a conduit to achieve the purpose of cleaning carbon deposits. 3. Machine cleaning, where cleaning agents are injected into a machine, pressurized into the combustion chamber to react and dissolve the carbon deposits, and then the waste liquid is extracted. This method has relatively good effects for severe carbon deposits and does not require engine disassembly, but the engine oil needs to be replaced after cleaning.
I've been thinking about carbon deposit cleaning for years, ever since I got my first car. At first, I tried fuel additives from supermarkets - cheap and convenient, but they only addressed surface issues without removing deep carbon buildup. Later, I switched to professional walnut blasting, where the shop uses high-pressure equipment to blast walnut shells into the intake tract. This method effectively removes stubborn carbon deposits without damaging components. After cleaning, the car starts faster and fuel consumption returns to normal. I believe this is the most thorough method with long-term effectiveness. Now I also take preventive measures: regularly driving on highways at high RPM for half an hour to let engine heat burn off carbon residue, and adding periodic cleaning agents for maintenance. Don't neglect air filter cleaning - dirty filters worsen carbon buildup. Timely treatment not only saves fuel but also extends engine life.
As someone who frequently works on cars, I highly recommend walnut shell blasting for carbon deposit cleaning. It uses specialized equipment to spray fine shells into the passages, physically grinding away carbon deposits without corroding the pipes—far superior to chemical additives. Additives only offer a temporary fix; when carbon builds up, blockages still occur. Disassembly cleaning is labor-intensive and expensive. I've seen many cars experience significant performance boosts after cleaning, especially older models. It's advisable to perform this every 20,000 kilometers, while also checking if the spark plugs and oxygen sensors are affected. For daily driving, remember to avoid prolonged idling and take longer trips to help clear residual deposits. This method is reliable and efficient, keeping your car healthy and reducing repair costs.
