1. If the automobile water tank scales, it can be cleaned and removed with water tank cleaner. The general cleaning agent can't completely remove the scale and acidic substances in the waterway, and sometimes it can soak off the large scale that falls off, but this will block the waterway, and sometimes it is necessary to remove the water tank for cleaning. If a powerful cleaning agent with good quality is used, the scale will be suspended in the coolant in the form of powder and will not block the water channel in the engine. Therefore, when buying water tank cleaning agent, don't just look at the cheap.

2. Manual cleaning method: it is necessary to remove the car water tank and remove the scale with a manual hammer, scraper and shovel; The descaling efficiency is low, the labor intensity is high, it is not easy to clean, and it is easy to cause secondary damage to the water tank.

3. Ordinary scale cleaning agent: the water tank needs to be disassembled, which is not complete, has a strong smell and is corrosive, and easily leads to the aging of the water tank and shortened service life.

4. Professional cleaner for automobile water tank: it can be cleaned without disassembly or without stopping the machine. The special scale remover can be directly poured into the automobile water circulation system. After soaking, idling or driving for 20-30 minutes, the scale remover in the water tank and system can be discharged. By washing with water repeatedly, the scale, rust, mud and various harmful substances in the engine water circulation system can be effectively removed.

5. In addition, to avoid the generation of scale, we should pay attention to the choice of coolant in the water tank. Many drivers do not pay attention to the use and advantages and disadvantages of coolant, and usually only add ordinary water to the water tank. The most common problems in cooling system are rust, scaling and corrosion. The main reason for this situation is that no good antifreeze is used. A good antifreeze not only has a low freezing point, but also contains other additives with various functions, which can inhibit foam, prevent rust, prevent electrolysis, prevent scale and so on.
