How to Descale Your Kettle: Limescale removal tips

Your kettle is your friend – a friend without whom you cannot prepare the long-awaited cup of tea on a beautiful rainy afternoon. Yes, the day feels less grey with a cup of tea in hand and you can thank your kettle for that. However, the more you use your kettle, the more limescale will build-up on the inside of it.

Why does this happen? How to descale your kettle and get rid of those chalky deposits? Read on to find out!

This article is for you if you:

  • Own a kettle;
  • Have noticed tough deposits on the inside of the kettle;
  • Wish to keep your kettle clean.

But… before you do anything, check the instruction manual from your kettle’s manufacturer. You might find important information about its proper maintenance.

What is limescale?

You will recognise limescale by the tough, milky deposits on the inside of your kettle. This is pure calcium carbonate and when left untreated, it can build-up to the point where it could clog up hard to clean spaces inside your kettle. 

Recent research has stated that over 60% of the water in Britain is hard, containing high amounts of minerals. So, when the water in your kettle boils and evaporates, it leaves miniature deposits of those minerals. Over time, they build up and solidify, making them difficult to remove. 

Scrubbing is not a good option to remove limescale, as it could damage the inside of the kettle. The good news is that mild acids are an effective option.

Tools you need

  • Distilled white vinegar;
  • Water;
  • Microfiber cloth.

How to descale your kettle with vinegar

Time needed: 15 minutes.

So, now that you have your tools ready, it’s time to get to work. Here is how to clean limescale from a kettle using white vinegar.

  1. Pour vinegar and water into the kettle.

    Mix equal parts water and vinegar inside the kettle. If the scaling on the inside is too harsh, you can add more vinegar than water.

  2. Bring the kettle to a boil.

    Place the kettle on the burner, or if it’s an electric kettle, switch it on. Let the water and vinegar boil to descale the inside.

  3. Let it soak.

    Once the water has boiled, switch the kettle off, or remove it from the burner, and let it sit for about 20 minutes. After that, pour the solution out and check the inside. There should be less scaling, and whatever is left should be easy to remove manually.

  4. Wipe with a microfibre cloth.

    Use a microfibre cloth or a non-metallic sponge to scrub the interior of the kettle. Do not scrub the heating element on the bottom of the electric kettle.

  5. Rinse.

    Rinse the kettle with water. It will take some time to completely remove the vinegar smell, so make sure to rinse multiple times. If you still can’t get rid of the smell, boil clean water inside and then dump it. This should do the trick.

How to descale your kettle using lemon juice

If you don’t like the smell of vinegar or if the manufacturer of your appliance is suggesting not to use vinegar for descaling, consider using an alternative method, for example, with lemon juice.

Simply mix 30ml of lemon juice with 500ml of water and pour the mixture into the kettle. Let the solution sit for an hour and then boil. If you’re dealing with stubborn limescale deposits, repeat these steps. Then rinse the kettle, pour fresh water and boil again. Rinse again, if needed.

How to clean the exterior of a kettle

The inside of your electric kettle indeed gets the worst limescale build-up. However, this doesn’t mean you should neglect the exterior of your appliance. Here is how to clean the exterior of your kettle:

  1. Clean the exterior with dish soap. Use a microfibre cloth to rub dish soap on the exterior of the kettle to remove dirt, rust or fingerprints. Make sure to clean the kettle like this on a weekly basis. After you clean it, wipe it dry with a paper towel.
  2. Polish the exterior with olive oil. If you have a stainless steel kettle, you can polish it after the clean to keep it shiny like on the day you bought it. You can use olive oil for that, but you’ll get relatively the same result with baby oil or mineral oil. Just place some oil on a soft cloth and rub the exterior. Wipe it dry with a paper towel if you put too much on.

How to clean a burned kettle

It’s not uncommon to put the kettle on the burner and forget it there. The water would boil and evaporate. The moment there is no more fluid, the surface starts to burn. By the time you remember, you might be left with a damaged kettle. The truth is that kettles are designed to only hold a specific temperature for a specific amount of time. If the temperature passes their breaking point, they can lose their structural integrity.

It’s up to you to decide whether you dispose of the kettle after it’s been burned, or try to save it. Here are a few helpful tips on the matter.

  • Wait for the kettle to cool down. Never attempt to assess the damage if you just removed the kettle from the burner. Wait for it to cool down on its own.
  • Wash the kettle. Use general dish soap to thoroughly clean the exterior and interior of the kettle. Sponge away the caked ash and burn marks if there are any. 
  • Assess the situation. If your kettle withstood the wash, then you might have saved it in time. If your kettle is made of stainless steel, it’s most probably safe to use again, as long as the bottom is solid and the spout is straight.
