Is it necessary to disassemble and clean the throttle or not?

For the cleaning of throttle valve, disassembly cleaning is the best. Because cleaning the throttle valve is mainly to clean the colloidal carbon deposit of the throttle valve body, which is the most important for cleaning the throttle valve piece, but the carbon deposit is mostly generated on the back of the throttle valve piece, and it is not thorough to clean the back without disassembly. Therefore, it is suggested that the disassembly effect is good, and it has no effect on engine disassembly and cleaning.
