Nowadays, every family owns at least one electric kettle and uses it every day. However, there is one thing about the device that not everyone pays attention to. It can even be said that many people ignore it. That is cleaning the kettle.

On a forum about household appliances, images of the inside of an electric kettle that has been used for a long time but not cleaned have received a lot of interaction. Specifically, white and yellow dirt and plaque are concentrated at the bottom of the kettle. Experts explain that these are harmful impurities, even bacteria that grow for a long time in the electric kettle, originating from calcium and magnesium in the water.

Although people boil water every day with the device, if not cleaned, dirt and plaque from the water source or the environment can accumulate. This causes plaque as in the image. In addition, not cleaning for a long time can also reduce the efficiency and lifespan of the electric kettle.
