Is Carbon Cleaner Useful?
2 Answers
Carbon cleaner is useful. Engine carbon cleaner is formulated with highly effective surfactants, detergents, corrosion inhibitors, and other additives, appearing as a colorless transparent liquid. It is diluted with water at a concentration of 3% to 6% during use. The cleaner has strong washing capabilities for various oil stains, including mineral oil, animal and vegetable oils. Carbon deposits refer to a coking-like substance produced by unsaturated olefins and gums in fuel under high temperatures during engine operation. If you experience slow acceleration, backfiring when accelerating sharply, or difficulty in cold starts while driving, it is likely that the engine valves have carbon deposits. If you notice low idle speed, engine shaking at idle, throttle sticking when pressing the accelerator, or no idle speed after replacing the battery, it indicates severe carbon buildup in the engine's intake pipe.
I've been in the auto repair business for decades, and car owners often ask if carbon deposit cleaners really work. These products do have some effect, especially for mild engine carbon buildup, such as clogged fuel injectors or carbon deposits in the intake manifold. Adding a cleaner to the fuel tank and taking a highway drive can usually remove some of the buildup, making throttle response much sharper and slightly reducing fuel consumption. However, it's not a fundamental solution. For severe carbon buildup, like stuck piston rings, cleaners are ineffective, and manual engine disassembly is the reliable way to go. I recommend using a reputable brand every 5,000 kilometers for maintenance, combined with regular oil changes and air filter replacements, which can extend engine life and save money. Using cheap products recklessly can harm the car, so it's safer to choose OEM or certified products. Gentle driving habits and avoiding frequent short trips can also reduce carbon buildup sources, keeping the overall maintenance system healthier.
