The best method to remove rust from a car radiator is to use a professional car radiator descaler. The steps are as follows: 1. Directly pour the dedicated scale remover into the car's water circulation system. 2. Let it soak, idle cycle, or drive for 20-30 minutes. 3. Drain the descaler from the radiator and the internal system. 4. Rinse repeatedly with water to effectively remove scale, rust, mud, and various harmful substances from the car radiator. Additional information: 1. The radiator is part of the car's cooling system: The radiator in the car's cooling system consists of three parts: the inlet chamber, the outlet chamber, the main plate, and the radiator core. 2. There are two main materials for radiators: aluminum and copper. The former is used for general passenger vehicles, while the latter is used for large commercial vehicles.
