How to Remove Carbon Deposits in the Car?
3 Answers
Solutions for removing carbon deposits in the car are as follows: 1. Clean the throttle valve and intake tract: Use carburetor cleaner to spray the throttle valve and intake tract. 2. Use an IV drip method: Fill the 'IV drip' with pressurized and atomized cleaning agent, then inject it into the intake tract to react with carbon deposits in components like the throttle valve and fuel injectors, dissolving them. Then, use high engine speed to blow the removed carbon deposits out of the engine. 3. Use 'cleaning agents': Pour a specific cleaning agent into a machine, pressurize it, and spray it into the combustion chamber to react with and dissolve the carbon deposits, then extract the waste liquid. 4. Use fuel additives: Long-term use of cleaning-type fuel additives, though not as thorough as advertised, still has some effect. 5. Disassemble and clean: Disassembling and cleaning is the most effective method for removing carbon deposits, though it is relatively more troublesome and expensive. 6. Drive at high speed: Theoretically, driving at high speed with increased engine RPM increases air intake, which can help flush out some carbon deposits.
As a frequent driver, I've found there are quite a few ways to remove carbon deposits from the car, and some can be done DIY. The simplest method is using fuel additives like tank cleaners - they gradually clean carbon deposits as the gasoline burns. Another effective way is taking weekly highway drives, maintaining high RPM for about half an hour to burn off deposits with heat. Regularly checking air filters and replacing spark plugs also helps prevent impurity buildup. For severe cases like unstable idling, professional cleaning with specialized equipment (like drip-style cleaners) can remove most deposits in one session. Driving habits matter too - avoid constant low-speed driving or frequent start-stops, and always warm up the engine properly. Remember, carbon deposits gradually damage engines and reduce fuel efficiency, so early treatment saves money!
As a driver who prioritizes long-term vehicle health, preventing carbon buildup is key. In daily driving, avoid prolonged idling—like turning off the engine at red lights during traffic jams—to reduce carbon deposits. Regular use of high-quality engine oil and timely maintenance, such as replacing air filters and spark plugs, helps keep the engine clean. If carbon buildup has already occurred, adding a fuel system cleaner to the tank or manually cleaning the throttle body with a soft brush can help. For stubborn cases, professional shops offer deep cleaning services with advanced equipment. Developing these habits leads to smoother performance, better fuel efficiency, and extended engine life—small steps that add up to big benefits.
