1. Try to avoid dry burning. Do not heat the Kettle when there is no water in it. Repeated and continuous dry burning will shorten the lifespan of the Iron kettle and may even cause it to crack.
2. Prevent large temperature differences. A large temperature difference refers to a significant difference between the temperature of the kettle body and the water temperature. For example, adding hot water to a cold kettle or Pouring cold water into a hot kettle. In such cases, there is a risk of cracking the kettle. A better approach is to alternate the use of two or more iron kettles. When you only have one kettle, you can replenish the water inside by adding hot water.
3. Keep the iron kettle dry. If there is still moisture left inside the kettle after use, it can easily rust. Therefore, you should use the residual heat from the kettle and stove to evaporate any remaining water inside, ensuring that the kettle stays dry.
