How to clean three-way catalytic converter in 4S shop

Hello: With regard to your inquiry, all brands of 4s stores now use disassembly-free cleaning methods to clean carbon deposits, such as disassembly-free cleaning of air inlets, disassembly-free cleaning of fuel injectors and disassembly-free cleaning of three-way catalytic converters. With the cleaning equipment, carbon deposits can be cleaned without disassembling parts to start the vehicle, and only the throttle body and idle valve need to be removed for cleaning. If the vehicle is driving in the urban area for a long time and the road conditions are poor, it is suggested that the vehicle should clean the fuel injector, air inlet and three-way catalyst every 30,000 kilometers.
