Limescale, that persistent white nuisance, is bound to take up residence in your kettle over time, be it electric or one you place straight on the hob.

Not only is limescale an eyesore, but it’s also a bit of a palate-offender in your cup and let’s not talk about how it can wreak havoc if left unchecked.

Whilst not harmful in itself, its presence could see you forking out for a new kettle more often than you’d like.

The go-to remedy, white vinegar, does the trick against this ancient issue, however, the stench it leaves is enough to turn anyone off their tea.

Cleaning buffs might have something up their sleeve as there is a product that zaps away limescale rapidly with zero smell involved – citric acid.

One desperate plea on the Mrs Hinch Army Cleaning Tips Facebook page caught the eye of fellow cleaning fanatics as Jo Besant reached out: “So this is the kettle at my work, they won’t buy a new one. Any ideas where to start, please? I’d like to have a cup of tea!”

Some suggested leaving white vinegar to soak in the kettle, but Anna Walker had a faster fix, recommending citric acid, boasting: “Citric acid is natural and no chemicals. Just mix with a bit of water and put it on to boil.

“It’s like very concentrated lemon juice. I usually leave it for about 10 minutes. I have hard water here and it is a lifesaver.”

Maxine Taoka explained: “Citric acid is a descaler and works wonders on kettles. I work in a lab, and we use it for our industrial water still and our kettle in the office.

“You can buy boxes of it in B&Q, and I’m sure I’ve seen it in Poundland too. Boil the kettle, add half a box and it dissolves all the limescale in 10 minutes.

“Stuff a bit of kitchen roll soaked in the solution for the spout. Remove the filter and chuck it in the main kettle as it works.”

Jess Holmes remarked: “Citric acid is what I use on my kettle and it works a treat. Would recommend using two tablespoons. Don’t like the smell of vinegar.”

Dan Moore asserted: “I’ve found citric acid works faster than actual lemons and white vinegar.”

After trying citric acid on her limescale-riddled work kettle, Jo exclaimed: “It’s amazing – put water in the kettle just above where the limescale stops, boil it then add three tablespoons of citric acid and let it sit for eight minutes, then rinse – no scrubbing required.”
