Limescale gradually accumulates below the waterline in a toilet, and if not addressed, it can become challenging to eliminate.

Some cleaning gurus suggest using a knife to scrape off thick limescale, while others advocate for the use of potent yet harmful cleaning products like bleach, followed by scrubbing to get rid of any residue.

Coca-cola and white vinegar have also been suggested as an inexpensive and non-toxic ingredient that dissolves limescale.

Domestos has shared everything households need to know about toilet limescale. They explained: “Limescale is a hard, chalky deposit that is the result of calcium, magnesium, and other minerals in hard water.

“With water constantly in contact with the bottom of the toilet, you get a greater build-up of limescale. The longer the limescale builds up the harder it is to remove.”

Limescale is “most evident as a coloured stain in your toilet bowl”. While limescale is naturally white, it changes to “various hues of green and brown” due to “germs and soil” that attach to the surface area.

The experts continued: “A biofilm [then] develops and it can take on various hues (green/brown) due to the pigments and slimes produced by the bacteria and soil that attaches to it.”

Having decided to give the Domestos Zero Limescale toilet cleaner ago, the Instagram page @apeagyei_house was shocked by the results.

According to the Domestic website, this product “kills 99.9 percent germs and removes 100 percent of limescale” and is “three times better than bleach ordinary toilet cleaners”.

To apply, simply open the bottle and squirt the gel evenly around the rim of your toilet, leave it for 30 minutes (following the directions on the bottle) and then flush away.

Alternatively, households can pick up Harpic’s Power Plus toilet cleaner which works well to remove toilet limescale and is said to be better than bleach. This retails for £1.99 at Nisbets and for around £1.50 at local supermarkets.
