Limescale deposits form wherever they come into contact with water on a daily basis. This is why toilet bowls, taps and showers quickly look dirty.

ScaleGuard said around 60 percent of the UK has hard or very hard water.

This means that most of the water that flows through taps and toilets in the UK has high mineral content.

These minerals, such as calcium and magnesium, lead to limescale deposits in the home.

When limescale builds up in the toilet bowl, it’s time to clean the toilet.

While bathroom retailer Victoria Plum said bleach, white vinegar and baking soda can remove limescale, there’s one household item you may not know about.

WD40 is “really good for removing limescale from your toilet,” noted Victoria Plum, as it is “particularly good at softening rust and limescale deposits in the toilet.”

Victoria Plum advises: “Just spray it on the desired area on the toilet, wait a few minutes and then scrub it away with a toilet brush.”

“You can also solve the same problem with WD 40 in the bathroom or sink. It will remove limescale stains and deposits and make your toilet look much brighter.”

With bleach, however, it can take up to 30 minutes for it to take effect and remove the limescale.

Using white vinegar can take even longer; it usually requires an overnight layer of limescale to remove it.

If you mix white vinegar with baking soda, it may be enough to let the mixture sit on the limescale for 10 minutes before it starts to work.

However, the solution may take about 25 minutes longer to remove limescale deposits, while WD40 can remove them within minutes.
