What is the noise after cleaning the throttle?

After cleaning the throttle, there is no carbon deposit on the throttle, the idle speed becomes stable, and the air intake is a little larger than before. There are two ways to clean the throttle, one is to wipe it on the cloth with chemical cleaning spray, and the other is to spray the throttle cleaning agent into the throttle after cleaning. I don't recommend spraying it on the accelerator, it will definitely get louder after spraying. It takes some time to get used to it.
