Will cleaning the throttle in the car suck dirt into the body?

The throttle cable is directly connected to the throttle, and the sludge attached to the throttle wall will hinder the normal opening of the throttle wall and affect the smooth intake. In severe cases, the throttle will not move, and even these dirty things will be directly sucked into the cylinder block, causing permanent damage to the engine cylinder block. Therefore, for the cleaning of throttle valve in harsh environment, it should be cleaned every 10000 km or once a year, so as to completely ensure the cleanliness of cylinder!
