How to clean the car air intake grille?

Cleaning method of automobile air intake grille: adjust the pressure of water gun to a low state, do not open the front cover of the automobile in advance, clean the air intake grille with water gun, and spray water from top to bottom, otherwise water will splash on the air intake. The air intake grille is located in front of the engine and its main function is to provide air intake and heat dissipation for the engine. When a car is driving, dust is most likely to accumulate in the front of the car, especially when it is driving at high speed for a long time. When driving at high speed, the air intake grille of the front of the car will be covered with leaves and dirt. Even if the car stops, there will be many bugs crawling into the air intake grille, blocking the air intake grille, reducing the efficiency of the cooling system in the car, resulting in the long-term high temperature of the engine, which can not work normally, thus reducing the life of the engine.
