Can Honda's cleaning agent solve the problem of carbon deposition? How does Honda clean up carbon deposits?

Can Honda's cleaning agent solve carbon deposition? Of course. Honda's cleaning agent has three cleaning methods: 1. Additive cleaning (fuel treasure): the cleaning agent is directly injected into the burning automobile fuel tank, mixed with the fuel, and enters the combustion chamber together with the fuel to clean the carbon deposit inside the engine; 2. Bottle washing: also known as disassembly-free cleaning, the cleaning agent is sucked into the combustion chamber in the form of bottles through the intake pipe of the engine to clean the carbon deposits in the intake pipe and the combustion chamber; 3. Disassembly and cleaning: Remove and clean the parts with carbon deposits. Although the cleaning effect is good, the working hours are long, and most 4S shops do not provide disassembly and cleaning services.
