How to lubricate the excelle throttle

First of all, I bought an electronic accelerator cleaner online and considered the suggestions of some riders. I didn't use the general carburetor cleaner, the power lion. Then disassemble the throttle for cleaning, and the cost of self-cleaning is about 50 yuan. However, I suggest you go to the 4S shop to clean and lubricate it. If it helps you, please set the best answer.
