What are the precautions for cleaning the car throttle?

Matters needing attention in cleaning the automobile accelerator are as follows: 1. Use special cleaning agent for throttle. If there is no special cleaning agent, when using carburetor cleaning agent, please spray the cleaning agent on a clean soft cloth first, and then wipe it repeatedly with a soft cloth to remove carbon deposit or sludge; 2. The throttle valve can be cleaned without disassembly, but the sealing part must be cleaned; 3. When cleaning the throttle valve, first remove the intake throat, expose the throttle valve, remove the negative electrode of the battery, turn off the ignition switch, straighten the throttle plate, spray a small amount of carburetor cleaner into the throttle valve, and then carefully scrub it with polyester rag or high-spinning non-woven fabric; 4. When the throttle is removed, some air pipes are connected around the throttle. When removing the throttle, be sure to remember the position of each pipeline and install it after cleaning.
