Have you ever gone to take a sip of your treasured morning cuppa and experienced an unpleasant hard lump hitting your lip? That will be the limescale.
We have some high standards about how we like to take our tea –- and with a spoonful of limescale is not one of them. So it's always good to know how to descale a kettle so you can make the perfect cuppa every time.
What is limescale?
Limescale is a hard, chalky mineral deposit of calcium carbonate that builds up inside kettles when hot water evaporates and solidifies.
Why do we need to remove limescale?
Not only is it extremely unpleasant to find hard lumps of limescale floating in your tea, it's important to keep your kettle free of limescale as it can slow down the heating process.
Limescale builds up in layers around heating elements so more energy is required when heating water. The result is a reduction in efficiency and an increase in running costs.
It's particularly important to descale your kettle around once every three months in hard water areas.

Next, you want get rid of the vinegar smell, so fill up the kettle with water and boil. Pour this water away and repeat the process until the vinegar aroma has gone. If you don't want to use vinegar, you can also try using natural lemon juice for this process too.
