Can cars clean up their own carbon deposits?

The carbon removal by hanging bottles in 4s shops is basically a good engine oil used in scams, such as the ash shell with strong cleaning ability, regular use of gasoline additives, not too weak driving style, and frequent high-speed driving, which can effectively remove carbon deposits in places such as oil nozzles and ordinary gasoline additives, because the engine oil will not flow into the combustion chamber, and ordinary additives will be ignited in the combustion chamber, which has no cleaning effect. But there are still advanced additives that can solve these problems. The throttle can be cleaned by itself, so don't go.
