To remove limescale, apply white vinegar (5% acidity) or a lemon-juice solution, let it sit for 30 minutes to 1 hour, then scrub with a non-scratch pad and rinse. Vinegar dissolves calcium carbonate deposits in 30 to 60 minutes. For heavy buildup, repeat or use a dedicated descaler.
Limescale is the chalky white residue left by hard water on taps, kettles, and tiles. Here is how to remove it safely surface by surface.
The basic vinegar method
- Warm 250 ml of white vinegar slightly to speed up the reaction.
- Apply directly or soak a cloth and press it onto the stain.
- Wait 30 minutes to 1 hour so the acid dissolves the deposits.
- Scrub with a non-scratch pad using small circular motions.
- Rinse thoroughly with clean water and dry to prevent new spots.
Method by surface
Match the technique to the surface, and never use acidic cleaners on natural stone like marble or granite, which etch on contact.
| Surface | Best method | Dwell time |
|---|---|---|
| Kettle interior | 50:50 vinegar and water, boil | 20 to 30 min |
| Taps and faucets | Vinegar-soaked cloth wrap | 30 to 60 min |
| Showerheads | Submerge in vinegar bag | 1 to 2 hours |
| Glass shower doors | Lemon or vinegar spray | 15 to 30 min |
| Marble or granite | pH-neutral cleaner only | Follow label |
Descaling a kettle
Fill the kettle halfway with a 50:50 mix of white vinegar and water, bring it to a boil, then switch off and let it sit for 20 to 30 minutes. Pour out, then boil with fresh water 2 to 3 times to remove any vinegar taste before next use.
Preventing future buildup
Dry surfaces after use, wipe taps weekly, and consider a water softener if your area has hard water above 200 mg per litre of calcium carbonate. Regular light cleaning prevents the thick deposits that take hours to remove.
Frequently asked questions
What is the best home remedy for limescale?
White vinegar at around 5% acidity is the most effective and affordable option. Lemon juice works well too, and both dissolve calcium deposits in 30 to 60 minutes.
Can I use vinegar on all surfaces?
No. Avoid vinegar and other acids on natural stone such as marble and granite, which etch on contact. Use a pH-neutral cleaner on those surfaces instead.
How do I descale a kettle naturally?
Boil a 50:50 mix of white vinegar and water, let it sit 20 to 30 minutes, pour out, then boil with fresh water 2 to 3 times to clear the taste.
How do I stop limescale coming back?
Dry surfaces after use, wipe taps weekly, and consider a water softener if your water is hard, above 200 mg per litre of calcium carbonate.
