How to descale a kettle
There are many methods to remove limescale from a kettle, from DIY descaling solutions using household products to commercial descalers. Below we have listed a step-by-step guide for each descaling method.
Vinegar & Water Method
- Firstly gather your supplies: white vinegar, water, a measuring cup and a soft cloth or sponge.
- Fill the kettle halfway with equal parts of water and white vinegar. We recommend using a measuring cup to measure a 1:1 ratio accurately.
- Bring the vinegar and water solution to a boil and let it simmer for 15-20 minutes – the acidic properties of vinegar will help dissolve the limescale buildup inside the kettle.
- Once the kettle has cooled down, carefully pour out the vinegar-water solution and rinse the kettle thoroughly with clean water multiple times to remove the solution altogether.
- Wipe the kettle’s interior using a soft cloth or sponge to remove any remaining residue. – use a utensil to scrape away any loose limescale gently
- After cleaning, fill the kettle with clean water and boil it once or twice to get rid of any lingering vinegar smell is removed.
Lemon Juice & Baking Soda Paste
- Create a paste in a bowl by mixing lemon juice and baking soda. Ensure the mixture is thick enough to spread quickly and smooth enough.
- Apply the paste directly onto the limescale inside the kettle. Using a soft brush and a sponge or cloth to spread the paste evenly.
- Allow the lemon juice and baking soda mix to sit on the limescale for approx 15-20 minutes. – this gives the mixture time to break down the mineral deposits
- After waiting for the paste to set in, scrub using a soft brush to gently scrub the areas with the paste and loosen the limescale.
- Thoroughly rinse the kettle with clean water to remove all traces of paste and limescale.
Citric Acid & Water Solution
- Gather citric acid, water, a measuring cup and a soft brush.
- Add one cup of water to your kettle.
- Measure 1-2 tablespoons of citric acid powder, add to the kettle and gently stir to help the citric acid dissolve.
- Boil the kettle, and let sit for 15-20 minutes.
- After waiting for the kettle to cool down, gently scrub the kettle’s interior with a soft brush.
- Empty the citric acid solution from the kettle and rinse thoroughly with water several times – we recommend boiling the kettle with water a few times to remove any remaining traces of citric acid.
- Using a soft cloth, wipe the interior of the kettle.
Use A Commercial Descaler
If these DIY descaling methods don’t work for you or you’d prefer a ready-made solution, you can use many commercial descalers. There are many acid-based descalers that you can buy, from sizes ranging from 1L to 5L commercial descalers.
- Depending on the descaler, carefully read the product label for specific instructions
- Ensuring you are wearing gloves, dilute the commercial descaler with water, using a container to mix the solution.
- Carefully put the prepared solution into the kettle, ensuring it covers the limescale
- Allow the descaler solution to sit for up to 30 minutes.
- After waiting, use a soft brush to scrub the kettle’s interior.
- Empty the solution and thoroughly rinse your kettle with clean water to remove all traces of the descaler.
