Descale an electric kettle

In this article, we exhaustively share the causes, elimination, and prevention of limescale on your electric kettle through natural methods.

What is Descaling?

Electric kettles are a great way to quickly and conveniently make tea or coffee. But over time, the mineral build-up from hard water can cause limescale to accumulate inside, affecting the flavor and performance.

Descaling is the total removal of limescale from the surface of a metal, especially from the inner surfaces of boilers and kettles.

What Is Limescale?

Limescale, which could also be called calcium scale, is most common in hard water. It is a hard, off-white chalky substance often found on the metallic parts of water-operated machinery. It is particularly common in equipment that involves heating such as boilers, electric kettles, or heat transfer systems (such as heat exchangers). So it is only natural that these scales are found on the surfaces of your kettle.

Hard water is known to be of utmost benefit to health. In fact, most mineral waters for sale contain minerals such as calcium and magnesium. These elements are good for your body as they have roles to play in the build-up of the body’s immune system.

 What Causes Limescale?

The accumulation of calcium and magnesium minerals in hard water causes limescale. This hard water is formed when rainwater filters through rocks like chalk and limescale, picking up hard minerals along the way. These hard minerals are not harmful to the human body.

Kettles get limescale because of calcium carbonate deposits and a residue left behind by hard water. When you heat up hard water at home, in your kettle, the minerals inside the hard water turn into limescale and cling to whatever they can, mostly the kettle’s inside.

Lemon Juice Can Break Limescale Deposits And Clean An Electric Kettle

Put a half cup of lemon juice into your kettle and wait for about 30 minutes. If the limescale is very thick, turn on the electric kettle, the lemon juice would heat up and break up the limescale; the steam caused by boiling would help steam up the rest of the kettle. (Repeat this step a couple of times if the limescale is really thick.) Allow boiling for some time, at least 2 to 3 minutes. Rinse thoroughly!
