Can I descale a kettle with vinegar?

Yes, for many kettles a mixture of white vinegar and water is an effective way to dissolve limescale. Check the manufacturer's care instructions first, especially for kettles with special coatings or filters.

How often should I descale my kettle?

It depends on how hard your water is and how often you use the kettle. Descale when you see a chalky mineral layer or flakes inside; in hard-water areas this may be needed every few weeks to a few months.

Can I use lemon juice instead of vinegar?

Often yes. Citric acid or lemon-based methods can also dissolve limescale, but concentrations vary. Follow the kettle manufacturer's instructions where available and rinse thoroughly afterward.

Why does my kettle still smell like vinegar?

Rinse it several times, then boil a full safe amount of fresh water and discard it. Repeat with fresh water until the vinegar smell and taste are gone.

For an electric kettle, unplug it and let it cool completely. Empty any remaining water. For a stovetop kettle, remove it from the heat and let it cool. Check the manufacturer's care instructions before descaling, especially if the kettle has a special interior coating or filter.
2. Add equal parts vinegar and water

Fill the kettle with a 1:1 mixture of white vinegar and water, using enough to cover the visible limescale without exceeding the maximum fill line. For example, use 500 ml (about 2 cups) of white vinegar and 500 ml (about 2 cups) of water for a 1 litre kettle.
3. Heat the descaling mixture

Bring the vinegar-and-water mixture to a boil using the kettle normally, unless the manufacturer specifically advises against boiling a descaling solution. Switch off or remove from the heat as soon as it boils. Keep your face away from the steam, which can smell strongly of vinegar.
4. Let the solution soak

Leave the hot vinegar-and-water mixture in the kettle for about 15–20 minutes. For heavier limescale, allow a longer soak after the kettle has been switched off. Do not leave an electric kettle plugged in while the solution is soaking.
5. Empty and rinse thoroughly

Pour the descaling solution away once the kettle has cooled enough to handle safely. Rinse the inside several times with fresh water. If accessible, wipe loosened residue gently with a soft non-abrasive cloth or sponge; avoid scratching heating elements or interior surfaces.
6. Boil fresh water and discard it

Fill the kettle with fresh water to a safe level, boil it once, then discard the water. Repeat if any vinegar smell or taste remains. Once the kettle smells neutral and the interior is free of loose residue, it is ready to use again.
