How often do you clean the 3008 1.6t throttle?

How often should this throttle be cleaned? There is no standard for this. It depends on your specific car condition. If you come to the new expressway area for a long time, it doesn't matter even if you don't use it, but if you are nearsighted in the urban area for a long time, it's best to suggest that you consider cleaning up the carbon deposits on the accelerator every 30 thousand kilometers.
