How to Clean Carbon Deposits in the Car Cylinder by Yourself?
3 Answers
To clean carbon deposits in the car cylinder by yourself, follow these steps: Open the oil cap, add a cleaning agent, mix it with the old engine oil, and let the engine idle for about 10 minutes. Methods to reduce carbon deposits include: 1. Perform regular car maintenance and change the engine oil; 2. Clean the car's air filter; 3. Replace the car's spark plugs periodically; 4. Clean the car's throttle body; 5. Avoid sudden acceleration and minimize hard braking; 6. Replace the car's fuel filter regularly. The main components of car carbon deposits are: 1. Metal debris from engine friction and wear; 2. Dust from the air; 3. Sticky substances formed from the oxidation, thickening, and acidification of engine oil under high temperatures; 4. Paint film produced by the oxidation and concentration of lubricating oil.
Here's how I previously cleaned carbon deposits from my car: mainly divided into three methods. The easiest is using fuel additives. Before each refueling, pour a bottle of cleaner into the tank—it can dissolve some carbon deposits, but you need to use it continuously for five full tanks to see results. If the effect isn't good, then disassembly cleaning is necessary—first unscrew the spark plugs, spray a dedicated cleaning agent into the cylinders, let it soak for half an hour, and then extract it with a syringe. This method allows you to see the black carbon deposits being soaked out. There's also a folk method: put the car in neutral and stomp on the accelerator, maintaining 4000 RPM for two minutes—the high temperature can burn off some soft carbon deposits. However, for severe carbon buildup, don't bother with these methods; if the piston rings are stuck, you must go to a shop for an IV cleaning. Prevention is key in daily use: avoid using low-quality gasoline, reduce idling time, especially in summer when waiting with the AC on—don't exceed half an hour.
I suggest being cautious when dealing with carbon deposits yourself, as improper handling can damage the engine. Fuel additives are the safest option—choose a reputable brand with PEA components and add one bottle every 5,000 kilometers. For disassembly cleaning, some DIY skills are required: prepare a T-socket to remove the spark plugs, and when injecting the cleaning agent, aim directly into the cylinder to avoid splashing other components. After cleaning, it's best to replace the engine oil to prevent residue contamination. Additionally, during quarterly highway drives, use a low gear and high RPM for about ten minutes to prevent new carbon buildup. Excessive carbon deposits are a major cause of high fuel consumption and poor performance. If you experience difficulty starting the engine when cold or notice black smoke from the exhaust, it indicates severe carbon buildup, in which case only professional walnut blasting cleaning will help. For prevention, remember to change the air filter on schedule, and avoid long-term use of ethanol gasoline in vehicles designed for mixed fuel.
