How To Descale An Electric Tea Kettle To Remove Hard Water Buildup

The video below shows how to descale an electric tea kettle, which has gotten a bunch of hard water build up on it.

For anything that gets heated on a regular basis, such as a tea kettle, hard water build up can be a real problem.

The reason for this is because there is already minerals in your water, but when you boil things the minerals don't always evaporate as quickly as the rest of the water and make a build up at the bottom of the item.

Hard water and lime scale build up are composed of alkaline materials, so anything which is mildly acidic in nature can remove it, such as vinegar, lemon juice, or citric acid.

In the video they seem to call lemon juice "citric acid," but in reality they are slightly different. Lemon juice does contain citric acid within it though, but if you purchase citric acid it is a more concentrated form than found in lemon juice.

You can either add a 1:1 ratio of vinegar and water, or 30 grams of lemon juice to 500 mL of water. If you don't want to be so precise just throw in a quartered lemon in with the water.

Boil the acidic liquid and water mixture in the kettle and then let sit to cool, and when you dump out the water, the scale will be loosened and gone.

The bicarbonate of soda (a.k.a. baking soda) suggested in the video is also alkaline in nature. Therefore, the video does not suggest using it for loosening the lime scale on the kettle, but instead for its abrasive properties once the mild acid has loosened it. That's because depending on how thick the lime scale was, you may need to physically remove it once it has been loosened.

After you've removed all the lime scale thoroughly rinse your kettle with water several times before using it again, or you'll taste either vinegar or lemon in whatever what you boil!

You can also put lemon juice with water to fill the kettle & boil. When boiled your kettle will be white again.

boil a lemon in it

Found the easiest way to clean the inside of a kettle like new without effort- I put half a lemon in the kettle, filled with water & boiled it, left it for 20 minutes, rinsed it out and it was like new. Easy & natural.

Pour a bottle of vinegar in your electric kettle and leave over night, rinse in the morning. No more white film.
