Does Carbon Cleaner Harm the Car?
2 Answers
It can cause some harm and damage to the engine. Engine carbon cleaner is composed of high-efficiency surfactants, detergents, corrosion inhibitors, and other additives, appearing as a colorless transparent liquid. It is diluted with water at a concentration of 3-6% during use. Currently, there are generally two methods for cleaning carbon deposits on the market. The first method: Using a related machine connected to the engine's intake pipe to inject the cleaning solution. The solution participates in combustion along with the engine, with gasoline as the main component and the cleaner as an auxiliary. The second method: Disassembly and cleaning involve removing the intake pipe and using walnut shells, dry ice, electric drills, etc., for cleaning.
Previously, I noticed increased fuel consumption after prolonged driving, and heard that carbon deposit cleaners could solve the issue, so I tried a well-known brand product. After following the instructions, the engine felt smoother, and acceleration was no longer sluggish. However, be cautious—using low-quality or generic brands may contain strong solvents that could corrode fuel lines or damage sensors, leading to significant losses. Ensure the engine is at normal temperature during use, and never spray while the engine is off. Additionally, avoid excessive or frequent use; cleaning every 20,000 kilometers is generally sufficient. Over-cleaning may strip necessary lubricating layers and accelerate part wear. I recommend checking product reviews first, choosing reputable manufacturers, and monitoring the car’s response after use. If there are unusual noises or vibrations, seek professional inspection immediately—safety first, don’t risk major issues to save a few bucks. Overall, when used correctly, it’s harmless, but caution is key to avoid minor gains leading to major losses. Regular full maintenance remains the best strategy for preventing carbon buildup.
