The Ultimate Guide To Descaling Your Electric Kettle

how to de-scale an electric kettle

Limescale, a buildup of minerals such as calcium and magnesium, is a common issue for electric kettle owners, especially in areas with hard water. This buildup can affect the taste of your tea or coffee and the performance of your kettle. Descaling, or removing limescale buildup, is a simple process that can be done using household items such as vinegar, lemon juice, citric acid, or baking soda. In this article, we will explore the different methods for descaling your electric kettle and provide step-by-step instructions for achieving the best results.

Using vinegar and water

To de-scale an electric kettle using vinegar and water, start by mixing one part vinegar and three or four parts water. Some sources recommend a 50:50 ratio, but a weaker solution of one part vinegar to three or four parts water should still be effective.

Fill your kettle with the vinegar and water solution. Then, bring the mixture to a boil, turn off the kettle, and let it sit for 20 minutes to an hour. After letting the solution sit, dump out the liquid and rinse the kettle thoroughly with fresh water. You can also wipe away heavy deposits using a soft sponge or cloth.

If you want to ensure that any lingering vinegar taste is gone, you can optionally refill the kettle with water, boil it, and discard the water.

How often you'll need to descale your kettle depends on how hard your water is and how often you use the kettle. Typically, you should aim to descale it around once a month or per the manufacturer's instructions.

Using lemon juice

Lemon juice is an effective, natural cleaner for descaling your kettle due to its acidity, which breaks down limescale and removes mineral deposits. This method is gentle on most kettle materials and can be used to clean the interior and exterior of your kettle.

To descale your kettle using lemon juice, start by ensuring your kettle is empty and cold. Then, fill your kettle halfway with water and add two tablespoons of lemon juice. You can use freshly squeezed or bottled lemon juice, as it is the acid in the juice that will break down the limescale. Next, bring the mixture to a boil, turn off the kettle, and let it sit for about 20 minutes. After 20 minutes, dump out the mixture and rinse the kettle thoroughly with fresh water. If there are any heavy deposits remaining, you can wipe them away using a soft sponge or cloth.

If you are struggling to remove limescale from the lid of your kettle, you can try soaking a damp cloth in lemon juice and placing it inside the lid before boiling. For the exterior of the kettle, you can rub lemon slices or use lemon juice directly on any problem areas. Finally, remember to rinse the kettle with water and wipe the bottom with a sponge or soft cloth.

If your kettle has heavy buildup or stubborn stains, you may need to repeat the process or leave the lemon juice solution in the kettle overnight before rinsing. Alternatively, you can use a more concentrated form of lemon juice, such as citric acid powder, which can be purchased online.

Using citric acid

Citric acid is a great way to de-scale your kettle, especially if you live in a hard water area, as it is a natural, non-toxic, and effective method. It is also a better option than vinegar, as it is a reducing agent and a weak acid, so it is effective in more situations than vinegar.

To start, put a little water in your kettle—enough to cover the heating element halfway down and all of the limescale present, which is normally about halfway full. Then, open the citric acid and pour in 2 heaped teaspoons or 1 tablespoon of citric acid powder. You can also use lemon juice instead of citric acid, which will have the same effect.

Now, turn on the kettle and watch the chemical reaction start to happen with the water and the citric acid. Leave the lid of the kettle open so you can keep an eye on it and ensure it doesn't bubble over.

Finally, turn off the kettle and let it sit for 20 minutes to half an hour. Then, pour out the water and rinse the kettle, and you're done! You should now have a shiny and limescale-free kettle.

Using baking soda

Descaling your kettle is important to ensure that your tea or coffee tastes as good as it should and to prevent the buildup of minerals, such as calcium and magnesium, which can shorten the lifespan of your kettle. Baking soda is a great option for descaling your kettle, and you may already have some in your kitchen.

First, remove as much free-floating limescale as you can by removing the filter in the spout, filling the kettle a quarter of the way full with water, and swirling it around. Next, create a paste with baking soda and warm water. Apply this paste to any affected areas, paying special attention to any seams, ridges, and spouts. Let the paste sit for 5 to 10 minutes with the kettle unplugged. Then, use a damp cloth or sponge to wipe away the paste and scrub off any remaining limescale. Be sure to avoid scrubbing the heating element.

For a deeper clean, you can add a few tablespoons of baking soda to the kettle after removing the paste, fill it three-quarters of the way with water, and leave it to sit overnight. In the morning, discard the solution and boil fresh water in the kettle two or three times to get rid of any remaining baking soda.

Always be sure to dry the base of the kettle and its electrical parts after cleaning to avoid any damage.

Using a proprietary kettle descaler

If you don't want to use home remedies like vinegar, lemon juice, or baking soda to de-scale your kettle, you can always buy a proprietary descaler.

There are many kettle descalers on the market, such as Urnex Dezcal, which can be purchased from Amazon and other retailers. Some descalers are made from 100% citric acid, which is a stronger alternative to vinegar and doesn't leave a lingering scent. One such product is Ecozone, which has accreditations from Allergy UK, Cruelty Free International, and the Vegan Society.

Before using any descaling product, it is important to consult your kettle's manual for cleaning instructions. Always follow the manufacturer's recommendations to ensure that your warranty is not voided. If no instructions are given for descaling, it is generally safe to follow these steps:

  • Ensure that your kettle is unplugged and allow it to cool completely before descaling.
  • Remove the filter from the spout, if applicable, and then fill the kettle around a quarter full with water.
  • Swirl the water and pour it out, repeating this process to remove as much solid limescale as possible.
  • Rinse the filter under a running tap to remove any limescale, then fit it back into the kettle.
  • Pour the descaling liquid into the kettle, leaving the lid open. Be careful, as boiling water can spit when adding a specialist descaling product.
  • Wait for the recommended amount of time for the solution to work, which could be approximately 6-8 minutes.
  • Discard the solution by pouring it down the sink.
  • Rinse your kettle with cold water, fill it with water again, and boil.
  • Get rid of the water and wait until your kettle has cooled, then dry it inside and out with a microfiber cloth.

Always take extra care to ensure that the base of the kettle and its electrical parts remain dry during the cleaning process.

Frequently asked questions

Descaling is the process of removing limescale buildup inside your kettle, which comes from calcium, magnesium and other minerals found in your water. If left untreated, limescale buildup can shorten the lifespan of your kettle and affect the taste of your drinks.

Typically, you should aim to clean your kettle around once a month or per the manufacturer's instructions. How often you'll need to descale will depend on how "hard" your water is (as hard water contains more mineral deposits) and how often you use the kettle.

You can use white vinegar, lemon juice, citric acid, baking soda, or a premade descaling solution.

The process will depend on the product you use. If using vinegar, fill the kettle with one part vinegar and three parts water, bring the mixture to a boil, then let it sit for 20 minutes to overnight. Rinse the kettle thoroughly with fresh water, then boil and discard the water again to remove any lingering vinegar taste. If using citric acid, fill the kettle with water, bring it to a boil, add a spoonful of citric acid, let it sit for 10 minutes, then rinse with fresh water.
