Over time, limescale in kettles and kettles will gradually accumulate, and the poured water may appear white, and these white liquids are actually the limescale we are afraid of. The yellow and white scale is tightly attached to the bottom of the pot, the inner wall and the spout, and the water boiled in such a kettle not only has poor thermal conductivity, but also the water that comes out is not beneficial to human health.
However, we always feel upset when we see these stubborn scales, so it is necessary to remove them completely.
The mouth of the thermos is narrow and deep, which makes it very inconvenient to clean with a scouring pad or steel wool ball. So, is there any way to easily remove limescale?
The first method is to use theophylline to remove scale. We can pour the leftover tea directly into the kettle, let it sit for a while and then shake it, so that the limescale in the kettle will naturally fall off. Although this method is effective for thinner scale, it has limited effect on thicker scale.
The second method is to use potato peels to remove limescale. The leftover potato skins that we usually peel can be put into a pot full of limescale, add cold water and boil. Because potatoes contain a lot of natural starch, when exposed to high temperatures, they will form a solution with adsorption and detergent ability.
When the potato skins are boiled with cold water, the limescale will gradually melt, thus softening the limescale. Although this method cannot completely decompose the scale, it still has a certain effect on the thinner scale.
However, for thicker scales, the above two methods are not as effective. So, is there an immediate way to get rid of it easily?
The third method, in fact, is that the main component of limescale is calcium carbonate, which we can use to break down the reaction with acidic substances.
For example, you can use vinegar (or white vinegar) mixed with water at 10% and pour it into a thermos and then add water to dissolve. In this way, the water in the kettle will become cloudy, and a lot of limescale will naturally dissolve and fall off. Due to the stubborn nature of aged limescale, this method may require several attempts to remove it completely.
In short, through the three methods introduced above, we can easily remove limescale from kettles and kettles, and keep the home environment clean and hygienic.
