Iron teaware generally refers to the iron teapot, because the price is relatively low, so it is one of the most widely used metal teawares. People do not usually steep tea in iron teapots, but simply boil the water in iron teapots to improve the quality of the water. Iron teapots are very popular in Japan and are an important part of Sado.

The advantages of the iron teapot

Use the water boiled in the iron teapot to steep tea, which can improve the taste of tea. Because the water boiled in an iron teapot contains iron divalent ions, it tastes like natural mountain spring water and improves the taste. What’s more, tea steep from water boiled in an iron pot can increase the absorption of the Fe. Fe is a hematopoietic element, drinking the water cooked by the iron teapot can play a certain effect in supplementing the Fe needed by the human body and preventing anemia.

Iron teapots help tea flavor, but maintenance them can be a trouble for many people. The most common defect is rust since the teapot is made by iron, rust grows naturally. With a little rust can be used normally, but if you don’t pay attention, rust will grow more and more, forming large areas of rust spots, or even deposit into rust blocks, that is very annoying.

Maintenance of iron teapot advocates “prevention first, govern later”

Daily maintenance of iron teapot to prevent rust

Don’t wait until the iron pot rust, usually more maintenance, the iron teapot is not easy to rust, but also more and more moist!

The iron teapot cannot hold water for a long time. After drinking tea, dry it as soon as possible.

Do not boil the water to completely evaporate, on the maintenance of the iron teapot is not conducive to. Continued heating without the heat absorption of water will increase the temperature of the iron teapot and increase the rate of oxidation.

Do not add cold water immediately after you have boiled a pot of water. Wait a few minutes and allow the teapot to cool down slightly before adding cold water to minimize damage.

The rust on the surface of the pot has no effect on the water quality, but the rust is easy to spread, so it should be prevented from further rusting and corroding the whole teapot. Use a soft cloth to wipe it and better not to use a hard brush.

Once the formation of rust, rust should be treated early

As we all know, iron is most afraid of water and air. Rust is everywhere, also because it’s hard to isolate these two things, the lock on the door, long used umbrella, can grow rust.

Once rust forms, it spreads even in dry air. Rough rust condenses the steam in the air, absorbs it and stores it, so it is harder to prevent rust from spreading than to prevent rust from growing. So we have to treat it in the early stages of rust formation.

How does the chemical way treat the rust? It’s easy. Use an acid. Solutions such as sulfuric acid and hydrochloric acid can melt away the rust. Of course, the iron teapot is used for boiling water and steeping tea, so these chemicals cannot be used. Natural acid substances should be used instead.

Detailed process and method of iron pot derusting

If there are some rust spots in the iron teapot, it smells iron and the water it boiled also has a fishy smell. It must be treated as soon as possible, so as not to make the rust worse. To treat the rust on the inner wall of the iron teapot is mainly to dissolve the rust with acidic objects, and then to prevent further rust by forming a protective layer on the surface of the iron teapot.

Steep. First let the iron teapot steep with water for half an hour, with a soft brush to brush the inner wall, as long as it is not the thick rust, do not recommend the use of steel ball, it will damage the iron teapot. Pour the white vinegar full into the iron teapot, do not cover the lid, and let it soak for 24 hours.

Brush. After steeping, a part of the rust has dissolved obviously, then brush the inner walls with a soft brush. Scrape the thick, large pieces with a knife, and the small pieces are better brushed with a soft brush. The water outlet also cleans with cotton swabs fully.

Clean with water again after brushing, observe the derusting status, some serious places to brush again targeted.

Boiled. Next, boil water with lemon to further treat the rust. The specific operation is to cut two lemons into the piece and put them into an iron teapot and cook them with a small fire for about 3 hours. The amount of water should be added to three-quarters of the iron teapot because the rust of the iron teapot is mainly at the bottom. During this period, please pay attention not to let the water overflow and timely add water to avoid heating to dry. After cooking, continue to soak for 2 hours. Then brush the inner wall with a soft bristle brush and rinse with clean water.

Maintenance. After rust treating, the water after boiling can not see the rust in it anymore. However, at this time, you can still smell the strong smell of iron in the iron teapot. You can put 100 grams of tea into the teapot, add water and boil it in a small fire for several times until the smell of iron disappears.

Occasionally boiled tap water with the iron teapot, tap water’s water quality is hard, easy to form scale in the inner wall, and this layer of scale can isolate moisture and air, reduce the chance of rust.(not means tea stain, tea stain has to treat too)

To make good water quality, the iron teapot needs to be maintained carefully. Remember, prevention is the key, once the rust grows, treat the rust at once.
