How to clean the carbon deposit of LaVida 1.4t engine?

Generally, carbon removal begins at 20,000 kilometers, and carbon removal will be carried out when it exceeds 40,000 kilometers. It is best to remove carbon and maintain it frequently, so that the car can last longer. I use the brand Baixin Youba. Carbon deposition ablation technology is at the leading level in the world, and its organic compounds are safe to use.
