What are the methods for dealing with car carbon deposits?

Methods for dealing with car carbon deposits: 1. Clean the throttle valve, which mainly controls the air entering the engine. After removing the engine cover, take off the throttle valve, clean it thoroughly with a cleaner, remember to wipe it dry with a cloth, and then reinstall it to its original position; 2. Find a drip bottle filled with pressurized atomized cleaning agent, inject it into the air intake, where it will undergo a chemical reaction. Just let the engine run to clean it; 3. Use fuel additives, which are specifically designed to clean carbon deposits and can prevent their formation, but be sure to buy high-quality ones; 4. Take the car to a repair shop and let the mechanic disassemble the engine for a thorough cleaning.
I'm very familiar with carbon buildup. Simply put, regularly running at high speeds is the most hassle-free solution. When I drive on highways, I intentionally keep the RPM above 3,000 for about half an hour to ensure thorough combustion in the engine. I also use fuel additives for cleaning—pouring one bottle in before refueling, and after three or four tanks, the effects become noticeable. Of course, driving habits matter too—avoid constantly driving at low RPMs and don’t hesitate to step on the gas when needed. If carbon buildup is severe, a professional cleaning like an IV drip or disassembly may be necessary, but with proper prevention, these measures are rarely needed.
I have a few practical methods for dealing with carbon deposits. First, use a legitimate fuel additive—just add it before refueling, as it can dissolve gum deposits in the fuel system. I make it a habit to use it once a month, and the results are quite good. Second, highway driving is crucial—regularly running the engine under high load helps burn off carbon buildup. Additionally, during maintenance, have the mechanic clean the throttle body by spraying it with a dedicated cleaner after removal; it doesn’t cost much. If your car shows signs of reduced power or increased fuel consumption, carbon deposits are likely the culprit—in such cases, a thorough intake system cleaning is the most effective solution.
To deal with carbon deposits, the main approach is a three-step prevention method. First, choose fuel from reputable gas stations to minimize impurities. Second, avoid prolonged short-distance driving; instead, take at least a 30-minute trip weekly to allow the engine to fully warm up. Third, use reliable fuel additives, preferably those containing polyetheramine. If carbon buildup has already occurred, for mild cases, adding additives and driving on the highway can help. For severe cases, it's necessary to disassemble and clean the throttle body and fuel injectors. After cleaning, remember to replace the air filter to maintain the effectiveness longer.
