In our life, every family will have an electric kettle, which is convenient and time-saving to boil water. But when using it, pay attention to these two points, otherwise the water you burn is more poisonous than plastic. Come and see it with me!
1. Material of electric kettle
When using the electric kettle for the first time, we must pay attention to its material. Which material is better for electric kettle? Common liner 304, 306, 316, all belong to stainless steel. However, the national standard for stainless steel food is only GB9684, which means that all stainless steel food-grade materials must meet this standard. If other stainless steel materials do not meet the food-grade standard, heavy metals such as manganese will dissolve after being heated at high temperature.
Frequent drinking of this heavy metal water will cause certain damage to the body. Therefore, when purchasing an electric kettle, you must pay attention to whether there are corresponding safety signs on the kettle. Only the water boiled by an electric kettle of safe material can be safely consumed.
2. Electric kettle scale
We need to clean the scale regularly, which is also a headache for many people. The electric kettle has been used for a long time. If the inner wall is not cleaned, a thick scale will form, and it will feel a little slippery or calcified when touched by hand, which is very uncomfortable! These things are the accumulation of bacteria or impurities in the water. If it is not cleaned in time, drinking it may cause harm to the human body. The composition of this scale is not simple. There are calcium acid substances, heavy metals, bacteria and other mixtures accumulated in the water. Therefore, if we repeatedly heat the water, it will cause harm to the body, so be sure to clean the scale of the kettle regularly!
The method of removing the electric kettle is also very simple, safe and non-toxic. First, prepare fresh lemon slices. Lemons are weakly acidic, and citric acid is especially effective for removing limescale. Put lemon slices in a kettle to make a chemical reaction between the magnesium carbonate and make the scale fall off easily. We heat the water and let it sit for 10 to 15 minutes, then pour out the water, wash the electric kettle again and you can continue to use it.
