How to decale a kettle

Descaling a kettle is definitely one of those ‘i’ll get round to it eventually’ jobs. And when the time actually does come, it’s tempting to take the easy route and just buy a new one.

But it doesn’t have to be a chore; it can be super quick and actually save you money the long run – if you’ve read our guide on prolonging the life of your things, you’ll know it’s worth investing a little extra time and attention to take the pressure off your bank balance.

So without further ado, here’s two no-faff ways to descale a kettle:

White vinegar

Generally, white vinegar is a key go-to household ingredient in cleaning or stain removal, and it’s no different when it comes to your kettle:

Here’s how…

  1. Fill your kettle three quarters full using equal parts water and white vinegar
  2. Bring the contents to the boil and leave to cool
  3. Drain the solution and rinse the kettle thoroughly
  4. Now re-fill the kettle with water and boil again to get rid of any lingering aftertaste



Rather than buying white vinegar, if you’ve got your resourceful hat on and want to make the most of what’s lying around the kitchen – say, a single lemon – this is probably the guide for you.

Here’s how…

  1. Fill your kettle with water, three quarters full
  2. Cut your lemon in half and drop into the water
  3. Boil the kettle a few times (2-4) until the limescale starts to fall away
  4. If your kettle hasn’t been descaled in a long while, this process may need to be repeated a few more times. Alternatively, the lemon/water solution can be left overnight

Now you’ve got the technique nailed, it’s important to know how often you should be going through the motions. According to Philips, regular descaling not only prolongs the kettle’s life, but limits the risks of premature breakdown. In cases of normal use (up to five times a day), the following descaling frequency is recommended:

  • Once every 3 months if you live in a soft water area (up to 18dH)
  • Once every month if you live in a hard water area (more than 18dH)
