It enhances the flavor of Japanese tea, black tea, and coffee, creating a slightly different, luxurious moment. **The Basic Rule for Iron Kettles is "Boil Only the Amount of Water You Need"** Caring for an iron kettle starts with putting water in it when boiling water. The key is to **"boil only the amount of water you need."** Once the water boils, immediately transfer it to a pot or other container, and empty and dry the iron kettle. **How to Care for Your Iron Kettle for Long-Term Use** 1. **Dry Immediately After Use** - Pour out all the hot water, remove the lid, and dry the inside with residual heat. - If any moisture remains, heat it on low heat for about 30 seconds to dry it. - When drying, do not wipe the inside with a cloth (to avoid removing the limescale). 2. **Thoroughly Wipe the Surface Moisture** - Store the lid upside down to make it easier to dry. - Be careful not to overheat the kettle; after heating for about 30 seconds, dry it with residual heat. 3. **Do Not Remove the Limescale Inside the Iron Kettle** - White limescale may adhere to the inside of the iron kettle, but this is due to the mineral components of tap water and has a rust-prevention effect. - Do not scrape or scrub it off; by letting it develop as is, the iron kettle will be kept in better condition. **A Little Rust is Nothing to Worry About** You may see reddish-brown spots inside, but this is a natural phenomenon, and there is no problem if the boiled water is not cloudy or has no strange odor. With proper care, an iron kettle can be used as a lifelong tool. Please enjoy the charm of the iron kettle, which gains character the more you use it, in your daily life. ※This product is a vintage item.
