How to prevent stainless steel electric kettle from rusting due to water quality or other reasons during long-term use?

In daily use, stainless steel electric kettles are easily affected by water quality, environment and other factors when exposed to water and high temperature for a long time, resulting in rust or scale accumulation. Water quality is an important factor affecting whether stainless steel electric kettles will rust. Hard water contains high minerals. Long-term use may cause scale to accumulate on the heating element and the bottom of the kettle, causing friction between the scale and the metal surface, thereby accelerating the corrosion process. For this reason, choosing soft water or treated water for heating is an effective measure to prevent rust. If the tap water is hard, you can consider using a filter or water softener to filter the minerals in the water to reduce the negative impact of hard water on the kettle.
Avoiding long-term water storage in the kettle is also an important way to prevent rust. After each use of the electric kettle, pour out the water and wipe the inside of the kettle to avoid long-term retention of water, especially when the water is hard. Excessive water accumulation not only easily forms scale, but also provides conditions for metal surface corrosion.
When using, avoid boiling the kettle empty for a long time. Although stainless steel has good heat resistance, the metal surface temperature is extremely high when the kettle is in an empty state. The scale and dirt in the kettle may accelerate the oxidation reaction and cause damage to the stainless steel surface. Therefore, when using it, make sure that there is at least enough water in the kettle to cover the heating base.
In addition to usage habits, regular cleaning is also an important measure to maintain stainless steel electric kettles. Using white vinegar or citric acid solution to clean the inside of the kettle can effectively remove scale and impurities. Clean it once a month or every two months to avoid the accumulation of scale and impurities. If serious scale has formed inside the kettle, you can use a special descaling agent to clean it to restore the cleanliness and performance of the kettle.
In addition, the storage method will also affect the service life of the electric kettle. When not in use for a long time, it is best to store the kettle in a dry and ventilated place to avoid the residual moisture in the kettle reacting with the moisture in the air, causing rust on the metal surface. Check the status of the kettle regularly to ensure that it has not been damaged by the humid environment outside.
Try to avoid scratching the surface of the kettle with hard objects or sharp tools. Although stainless steel has a certain scratch resistance, long-term friction may damage its surface protective layer, exposing the metal and easily causing rust.
