What are the methods for cleaning carbon deposits in a car?

Methods for cleaning carbon deposits in a car: 1. Remove the engine cover, take off the throttle valve, clean it with carburetor cleaner, dry it with a cotton cloth, and then reinstall it; 2. Open the oil cap, pour in the entire can of cleaner, close the oil cap, start the engine and let it idle for ten minutes before turning it off; 3. Pour the intake system cleaner into the liquid storage tank of a dedicated cleaning device, connect it to the intake system, and start the engine to use vacuum to draw the cleaner into the intake tract for cleaning. Methods to identify carbon deposits in a car: 1. Check the fuel consumption; if the increase continues to rise, it indicates that carbon deposits have formed on the engine; 2. Based on the mileage, the higher the car's mileage, the more carbon deposits will accumulate; 3. Replace with higher-grade gasoline; if there is an improvement in power, it means there is more carbon deposit in the engine.

I've been driving family cars for over ten years and have encountered quite a few carbon deposit issues. There are mainly several cleaning methods: The simplest is adding fuel system cleaner - just pour a bottle into the tank when refueling. It can dissolve carbon residues in the engine, showing effects after driving a few hundred kilometers with slightly reduced fuel consumption. Another method is highway driving - maintaining high engine RPM for over half an hour to burn off deposits, which works particularly well for older vehicles. For severe carbon buildup (manifested as unstable idling or power loss), professional cleaning like throttle body removal cleaning or fuel injector cleaning with specialized equipment is necessary, but DIY attempts might cause errors, so it's better to visit a repair shop. Untreated carbon deposits affect engine lifespan and increase maintenance costs, making regular maintenance crucial. I recommend adding cleaner every 5,000 kilometers as prevention.

As someone frequently involved in car maintenance, there are several professional methods for cleaning carbon deposits. The most common is throttle body cleaning: removing it and spraying with a dedicated cleaner to remove sludge and carbon buildup. Fuel injector cleaning requires equipment to pump cleaner into the fuel system, thoroughly clearing blockages. Intake system cleaning is also effective by drawing cleaner through the vacuum hose. These methods require tools and skills, making DIY risky, so it's recommended to seek professional service. Carbon deposits can lead to reduced power and excessive emissions, and timely cleaning can extend engine life. I've seen many cars damaged by carbon buildup, resulting in higher repair costs, so don't delay. Using high-quality fuel and additives for prevention is best in daily use.

To save money on cleaning carbon deposits, I recommend using fuel additives. Buy well-known brands from the supermarket and add one bottle when refueling—it's cost-effective and works quickly. Another method is high-speed driving: take your car on the highway over the weekend, maintain high RPMs for half an hour to burn off the deposits, which is free and simple. Excessive carbon buildup leads to higher fuel consumption and sluggish acceleration, so address it early to avoid costly repairs. I've used these methods, and my car has stayed in good condition, saving me hundreds compared to garage visits. Avoid low-quality additives to prevent engine damage. Doing this periodically keeps your car running smoothly.
