What are the methods for carbon deposit cleaning?
2 Answers
For carbon deposit cleaning, it can be carried out under the following conditions: 1. Throttle valve carbon deposits: The throttle valve is a device located at the top of the combustion system that controls the intake air volume. Due to its working environment and nature, carbon deposits may form on this component. The most common cleaning method for throttle valve carbon deposits is to remove the throttle valve, clean both sides with carburetor cleaner, and then wipe off the decomposed carbon deposits with a cotton cloth. 2. Internal engine carbon deposits: Internal engine carbon deposits mainly appear on the intake and exhaust valves and the pistons in the combustion chamber. The best cleaning method is to find an experienced technician to perform a machine wash, which is more cost-effective and cleaner than using additives. Regular maintenance and timely replacement of the air filter are essential, and the use of low-quality gasoline should be avoided.
I enjoy working on my car myself and have tried quite a few methods for cleaning carbon deposits. The most common one is adding fuel additives to the gas tank and driving at high speeds to dissolve some of the buildup. Another method is cleaning the throttle body: just buy a spray can, remove the intake pipe, and give it a spray—simple and cost-effective. However, DIY methods are only suitable for mild carbon buildup. If it’s severe, the car will shake noticeably, fuel consumption will skyrocket, and it’ll pollute the environment. At that point, it’s best to take it to a professional shop for cleaning. I recommend doing this regularly—check every 10,000 to 20,000 km. Doing it yourself can save a few hundred bucks, but don’t push it too far. Make sure to have gloves and a mask ready—safety first, and avoid damaging engine components. Here’s a little tip: fill up the tank before adding the additive for more even distribution.
