Remove the intake throat pipe to expose the throttle valve; Disconnect the negative terminal of the battery and turn off the ignition switch; Straighten the throttle valve flap and spray a small amount of carburetor cleaner into the throttle valve; Use a polyester cloth or non-woven fabric to scrub, and for deep areas of the throttle valve, use a clip to hold the cloth for cleaning.

Valve carbon buildup is common in older vehicles, mainly caused by incomplete fuel combustion leading to impurities accumulating at the valve position, which affects engine power and fuel consumption. There are several cleaning methods, and the one I frequently use is chemical cleaning, such as adding professional carbon deposit cleaner to the fuel tank to dissolve the carbon deposits while driving. The operation is simple: first, buy a good-quality cleaner, pour it into the fuel tank according to the instructions, fill up with gas, and drive a few hundred kilometers. Another physical method requires disassembling the engine and scraping off the carbon deposits with tools, but this is risky and should be done by professionals. When I handle it myself, I always wear gloves to avoid skin contact with chemicals and check for any residue after cleaning. Prevention is also important; regular oil changes and using high-quality fuel can reduce carbon buildup. After my last cleaning, I noticed a significant reduction in fuel consumption and smoother acceleration. If you're not very familiar with cars, don't attempt disassembly; it's safer to spend some money and go to a repair shop.

Cleaning carbon deposits from the valves isn't difficult. As a DIY enthusiast, I prefer simple solutions. Just buy a carbon cleaner, pour it into the fuel tank, and drive to dissolve the deposits. It's easy and affordable. Before cleaning, check for any unusual engine noises to confirm it's a carbon buildup issue. Prevention is key—I use high-quality gasoline and regular maintenance to minimize problems. Once, my car had poor performance, but after using the cleaner, it improved. If you're unsure, consulting a professional mechanic is always wise.

Valve carbon buildup is a common engine issue, with chemical and physical cleaning methods available. I recommend using chemical cleaners—safe and efficient, just pour into the fuel tank and drive for a few days. Physical cleaning requires disassembly, which I leave to technicians. Post-cleaning tests show excellent results.

When carbon deposits on the valves affect driving, cleaning is essential. I usually choose a professional cleaner to pour into the fuel tank, allowing it to dissolve the carbon deposits as the gasoline circulates. Before operation, ensure the car is parked safely and handled securely. After cleaning, fuel consumption will improve, and I recommend doing it regularly to maintain the engine. Don't forget protective measures like wearing gloves. The effect is good and worry-free.

Valve carbon deposits can lead to weak power and pollution. I prefer using carbon deposit cleaners for cleaning. The method involves purchasing a suitable product, pouring it into the fuel tank, filling up with gas, and driving on the highway to dissolve impurities. It's easy to do it yourself, just wear protective gear to avoid harm. After cleaning, test drive to observe changes, and combine it with regular maintenance to prevent recurrence.
