Electric Kettle Limescale? How to Descale and Prevent It

Seeing chalky white flakes in your kettle or floating in your tea? That is limescale, the mineral buildup that hard water leaves behind. It slows boiling and shortens kettle life, but it is easy to remove.

Here is how to descale a kettle and keep scale away.

This article will teach you:

• What limescale is
• Why it matters
• How to descale safely
• How to prevent buildup

Why Limescale Builds Up

• Hard water leaving mineral deposits when it boils.
• Infrequent cleaning letting scale harden on the element.
• Leaving water standing in the kettle between uses.
• High mineral content in local tap water.

What You’ll Need

• White vinegar or citric acid
• Fresh water
• A soft cloth

How to Descale a Kettle

1. Mix the solution. Fill with equal parts water and white vinegar, or use citric acid.
2. Boil and soak. Boil, then let it sit 20 to 30 minutes.
3. Rinse well. Empty and rinse two or three times to remove any taste.
4. Boil fresh water. Boil and discard one plain load before using it again.

Pro Tip: Descaling every few weeks in a hard-water area keeps the element efficient. Emptying the kettle after each use, rather than leaving water in it, slows scale dramatically.

When to Look a Little Deeper

Because scale affects performance, it helps to connect it to other symptoms, and reviewing a kettle that will not boil, a kettle that shuts off early, or a plastic smell can reveal related issues.

When to Call a Pro

Descaling is fully DIY. If heavy scale has damaged the element so it will not heat even after cleaning, the kettle has reached the end of its life.
