How to descale a kettle: in just 25 minutes
And the winner ingredient is...no, it's not vinegar. Although vinegar is a popular cleaning ingredient for all over the house, it's not out first choice for removing limescale. Firstly, vinegar takes a while to work on limescale; secondly, we personally don't fancy the smell.
What you really need is citric acid, in powder form. It's the ingredient that products marketed as descaling sachets are made from, so you really don't need anything called 'kettle de-scaler', just food-grade citric acid.
Simply boil your kettle and add two to four tablespoons of the citric acid powder (or a sachet, if that's the format you're buying it in) to the boiled water. Leave to soak for 25 minutes. You will see some fizzing action. Simply empty and rinse. That's it. The easiest kettle de-scaling hack ever. What's even better is you can use citric acid for freshening up your washing machine, cleaning shower tiles and your shower head. It's as useful around the house as baking soda.
