Stainless steel electric kettles are widely used because of their rapid heating and good heat preservation performance. However, as the use time increases, a layer of white or yellow scale will gradually accumulate on the inner wall of the kettle. Although these scales are mainly composed of calcium carbonate and magnesium hydroxide, which are non-toxic and harmless to the human body, they not only affect the efficiency of boiling water, but also affect the appearance of the kettle, and even make people feel "unclean". Next, we will introduce several ways to clean the scale of stainless steel electric kettles.
1. Add chopped lemons to the electric kettle, fill it with water, and let it stand overnight.
The next day, you will find that the kettle has become as bright as new, and there is no vinegar smell left, and the fragrance of lemon will be emitted when boiling water. If the scale is thick, you can increase the amount of lemon appropriately.
2. Pour an appropriate amount of white vinegar and boil it with boiling water. The scale will dissolve quickly.
3. Use the method of boiling eggs to remove scale.
Put two egg shells into the kettle after they are slightly crushed, add half a teacup of cold water, seal the bottle mouth and shake it for 20 seconds. Pour out the eggshells and water, and then rinse with clean water.
4. Potato peels can also effectively remove scale.
Put potato peels into a pot with scale, add water until the potato peels just cover the potato peels, heat for 10 minutes, pour out the water and potato peels, and you will find that the scale will be discharged.
5. Use the principle of thermal expansion and contraction to remove scale.
When the empty pot is boiled dry until there are cracks on the bottom of the pot or a "bang" sound is heard, quickly add cold water or wrap the handle and spout with a rag and place it in cold water. Repeat this process 2-3 times, and the scale will fall off naturally due to thermal expansion and contraction.
Tips · How to prevent scale from accumulating again?
✅ Drain the remaining water in time after each boiling, and do not leave water in the pot for a long time;
✅ Clean it regularly once a week to prevent scale from accumulating;
✅ Use water filtered by a water purifier to significantly slow down the formation of scale;
✅ Avoid dry boiling to prevent the bottom from scaling too quickly or damaging the heating plate.
