How to Clean Carbon Deposits by Yourself?
2 Answers
When cleaning carbon deposits by yourself, you can use higher-grade gasoline, drive more on highways, and use fuel cleaning additives. Using Higher-Grade Gasoline: Higher-grade gasoline can effectively flush out residual carbon deposits. Compared to lower-grade gasoline, higher-grade gasoline has a higher octane rating, burns more completely and cleanly, and thus is much less likely to form carbon deposits. For example, if you usually use 92-octane gasoline and notice carbon deposits, you can switch to 95-octane gasoline for one or two tanks. Driving More on Highways: Driving on highways can utilize the airflow to clean the intake passages and prevent carbon deposits. Additionally, increasing the shift RPM has a similar effect. Changing gears at 2500 RPM instead of 2000 RPM not only effectively prevents carbon deposits but also enhances the car's power performance and avoids engine knocking caused by shifting at too low RPMs, thereby protecting the engine.
I have experience in cleaning carbon deposits from cars. Frequent traffic jams in the city can easily lead to buildup. The simplest method is using fuel additives, which can be bought at gas stations or online. Choose products labeled for carbon deposit removal and pour them into the fuel tank as instructed. The best results come when driving on the highway—maintain high RPMs for over 30 minutes to allow the engine to fully burn off the deposits. Don’t casually follow others in disassembling and cleaning the throttle body; beginners can easily damage sensors and end up spending more on repairs. If severe carbon buildup causes engine shaking, try foam cleaners—spray them into the throttle body from a can, wait 10 minutes, then start the engine. Adding a cleaning agent during each oil change can help with maintenance. Avoid 'IV drip' carbon cleaning services—they’re often scams and can harm your car. Always wear gloves and goggles for safety before starting any work.
