Limescale can truly become an eyesore in kettles, especially for those living in hard water regions packed with hefty amounts of calcium and magnesium.

Although consuming this buildup has no health repercussions, brewing a cuppa with floaty limescale flakes could indeed cause a blush or two in the presence of guests, reports the Express.

In the shift from stinging chemicals towards more eco-friendly alternatives, many folks are utilising white vinegar to restore sparkle or choosing baking soda for their cleaning needs.

However, for battling kettle limescale, one unconventional ingredient has cleaning enthusiasts buzzing lately.

Not knowing how to deal with her limescale-laden kettle, one woman requested: "Can I get some tips for removing limescale from my kettle, please? Ideally homemade."

Though numerous suggestions leaned towards white vinegar - which unfortunately tends to rake in time and emits an unpleasant smell - cleaning aficionados recommended citric acid instead.

Citric acid is a naturally abundant acid uncovered in various fruits and veg, but is accessible as a powdered substance.

Sporting impressive descaling capabilities coupled with de-greasing, anti-fungal, and anti-bacterial properties, it not only makes short work of kitchen grime but also shines in bathroom clean-ups.

Testifying its effectiveness, one person declared: "Citric acid is truly magical and totally cheaper than the normal descale stuff."

One comment read: "Citric acid. [Put a] spoonful of it in [the] kettle whilst boiling. Leave to cool and rinse."

Another comment read: "I use citric acid or white vinegar. Both work well but I'd say the citric acid worked better than the white vinegar because the results were instant."

Another cleaning fan also had her say: "Definitely citric acid, I've only just found out about this and it's brilliant."

She added: "I boiled the kettle with water and a tablespoon of the citric acid and as soon as it had finished boiling the limescale had gone."

A mere 250g box of citric acid from B&Q costs £2.25, which amounts to 14p per tablespoon.

For those keen on using citric acid for household cleaning tasks, Amazon retails 1kg of the product for £9.95.
