Most UK households will experience limescale deposits inside the toilet bowl that look brown in colouring.

One mum, fed up with the persistent limescale stuck to the inside of her toilet rim, took to the internet to seek support.

In a Mumsnet forum, the woman said: "Under the loo, rim has limescale that nothing I've so far tried can shift and it's starting to really bother me.

"Does anyone have any super limescale-busting tips? I've tried soaking it in supposedly limescale-tackling Toilet Duck, leaving and then scrubbing. Same with spray-on limescale remover. No luck. Anything else I could try?"

Comments came flying in with solutions, with one common theme reoccurring, which required no harsh chemicals nor excessive scrubbing.

A fellow user recommended: "I'd try soaking some loo roll in white vinegar, wedging it in there and leaving it overnight."

People agreed, with another adding: "Soak wedges of loo roll in vinegar or lemon juice and push into the rim.

"Leave overnight. The next day, run around the rim with an old spoon to remove softened limescale. Repeat as required."

Distilled white vinegar, which might already be in your kitchen cupboard, is an effective and economical option, with a price tag of just £1.19 for a bottle at Wilko and £2 at Ocado. 

Another Mumsnet user suggested an alternative way to tackle the hidden grime under the toilet rim.

She posted: "I squirted a load of limescale remover under the rim and then got up there with my hands, a knife and a flannel, dragging the flannel along under the rim – seemed to work well.

"Then I got a portable bidet bottle, filled that with hot water and squirted under the rim and the force of the water rinsed out a load of brown sheets of limescale - it's now perfect!"

As with any toilet cleaning method, it's best to wear protective gloves when removing limescale.
