What is the correct method for cleaning carbon deposits?
2 Answers
The correct methods for cleaning carbon deposits are as follows: 1. Throttle carbon deposits: The throttle is a device located at the top of the combustion system that controls the intake air volume. Due to its working environment and nature, carbon deposits can form on this component. The most common method for cleaning throttle carbon deposits is to remove the throttle and then clean its front and back with a carburetor cleaner, followed by wiping away the decomposed carbon deposits with a cloth. 2. Engine internal carbon deposits: These mainly accumulate on the intake and exhaust valves and the pistons in the combustion chamber. Additives can be used to clean carbon deposits in these areas; simply add the cleaning additive directly into the fuel tank.
Cleaning carbon deposits requires a step-by-step approach, starting with simple methods like using fuel additives. I often recommend car owners to choose well-known brand cleaners, which can be directly poured into the fuel tank during refueling to dissolve and expel carbon deposits. If the effect is not obvious, manual cleaning is necessary, such as removing the throttle body or intake manifold and scrubbing with professional solvents. In severe cases, it is recommended to seek professional shops for steam cleaning or walnut shell blasting treatment, which can thoroughly remove stubborn carbon deposits. However, be cautious—frequent use of additives may corrode engine components, and improper manual operations can damage valves or seals. Carbon deposits can lead to increased fuel consumption and insufficient power. Regular use of additives or maintaining high RPMs during high-speed driving can effectively prevent these issues. In short, safety comes first; if you're not familiar with the process, consult a technician for inspection.
