Easy method to banish limescale on taps with cheap items

If you’re tired of battling stubborn stains and limescale on your taps – especially when it’s thick, rock-hard and won’t shift – there’s an easy way to get your sink looking like new again.

Limescale is made up of calcium and magnesium left behind when water evaporates. Over time, it forms a hard, chalky crust wherever water sits, which is why taps and sinks are such common problem areas. But it can also build up in places like kettles, showerheads and toilets.

Thankfully, you can remove limescale from taps using natural remedies – meaning no harsh bleaches or strong chemicals. And all you need is some scrubbing tools and one key ingredient – white vinegar.

Experts at Cillit Bang suggest picking up a soft cloth or sponge, white vinegar, a toothbrush and a bowl. It says: “These items are essential for effectively tackling the limescale buildup on your taps.

“The soft cloth or sponge can be used for gentle scrubbing – with the bowl for soaking close at hand – while the white vinegar will act as a powerful natural cleaner.

“The toothbrush will help you reach those hard-to-reach areas.” But when you’re finished, don’t leave the toothbrush anywhere it could accidentally get mixed up and used for cleaning teeth – keep it separate (or bin it).

How to remove thick limescale from taps: step-by-step

Fill a bowl with white vinegar, then soak the limescale-covered parts of the tap so they’re fully submerged.
Leave it to soak for at least 30 minutes (longer for stubborn build-up), as the vinegar helps break down the limescale.
Once it’s soaked, use a soft-bristled toothbrush to scrub away the loosened limescale.
After soaking, gently scrub with a soft-bristled toothbrush to lift the loosened limescale. Then rinse with clean water and dry well with a clean cloth.

Is limescale dangerous?

BRITA, best known for its water filters, reassures that “limescale is not bad for your health.” It explains: “Limescale is naturally found in most water supplies, particularly in areas with hard water.

This is made up of calcium and magnesium carbonate and occurs when water is heated. This is why you often find limescale in the bottom of your kettle. Although this chalky substance might look unsightly, it’s not harmful to drink.”

Talking about the safety of UK tap water, BRITA adds: “If the kitchen sink tends to be your regular watering hole, you’re in safe hands. British tap water is said to be one of the best water supplies in the world, with a quality rating of 99.96% according to Discover Water.

“This quality is regularly monitored by the Drinking Water Inspectorate (DWI) to ensure our water is both clean and safe to drink. During these regulations, the DWI search for things such as E.coli and other bacteria across reservoirs in the UK, access the full report here.”
