What is the best way to remove limescale from a toilet bowl?

Currently there is a build up of limescale in the toilet bowl, where it isn’t getting flushed away.
I have tried some standard limescale removing products, but don’t seem to have any long-lasting effects on the bowl.
Is there any sure-fire options to clear away the limescale?
Ideally, something with industrial strength to make sure that it will be cleared.
Any other suggestions are also welcome if you’ve some success with other methods!
Thanks

"I use Domestos Zero Limescale remover on a regular basis. I put my gloves on, squirt generously around the underneath of the rim, leave for 30 minutes and use a brush if there are any stubborn areas but this is very rare, as I clean the bowl weekly. Then rinse by flushing the toilet a couple of times.
If there is a build-up you may have to do this 2 or 3 times a week to see a result.
I also use Harpic Bleach Toiler blocks in the toilet water tank.
Frequent cleaning is the best answer I can give you.
Hope this helps you.

"I personally come across some stubborn limescale that doesn’t shift with ‘viakal’ type products.
White vinegar is roughly £1, it’s the complete opposite compound to limescale and therefore eliminates it. If you have access to your toilet system, flush the toilet, hold the ball float up to fool the toilet and no water will go into the bowl, this may only be a useful tip if your toilet has a ball stop. It just avoid watering down products to get the most out of them.

Also try a steamer or a sharp one sided blade - regular use of a home limescale removed instead of bleach will prevent in the future.

"Hello,
There are so many methods and so many ways but it's all depends on the level of limescale. The one in the toilet is quite easy to get rid of.

I normally empty the water at first by using a cup and towards the end a cloth to absorb all the water until is dry. I leave inside different combinations of products depending on the level of limescale:
1. Bleach (plain liquid one)
2. One litre of vinegar + baking soda
3. Bleach + descaler
4. Bleach + fairy liquid (+descaler)

Some might argue that the bleach in its chemical composition does not remove scale but in my experience, it really breaks down the limescale especially when I had to deal with some up until the waterline level and thick.

I leave it for an amount of time, the more the better, sometimes I go around and add more bleach from time to time especially when I am in a rush.

I use a pallet knife or any sharp tool (even a spoon is helpful) to remove the chunks and slowly I add hot water in order to break it. Do not worry if the toilet bowl gets dark marks from the spoon or the tool you are using, you can use CIF afterwards and it will erase it. If it is not that thick you can use a sponge (the hard side).
If you use vinegar to clean and scrub it will be more effective. I use vinegar combined with baking soda to polish and disinfect the bath as well.

If you do not want to spent too much time scrubbing, keep on removing the water and leave 1 litre of vinegar overnight or during the day when you are at work and it will slowly go away and the toilet bowl will be shiny!!

At home, I use vinegar and baking soda for almost everything as I find it the safest and healthiest way than the exposure to chemicals.

Best of luck!"

"Lime or lemon products or even natural lime juice are very good choices. Personally, I use lime juice. A less nasty and natural solution to all your limescale troubles. Just add and leave it to work its magic."

"You can put bleach into the toilet bowl, leave it for about 10 minutes or overnight. That should get rid of the limescale."

"First plunge away as much water from the bowl as possible,then pour in some brick acid,,gloves and eye protection should be used ,leave the brick acid for 30 mins or more and scrub with toilet brush,avoid scraping as this can damage the porcelain ,if needed repeat the process,keeping the window open as there may well be some fumes,
hope this helps"

"I've always had great success with a liter of cola poured down the loo and left for at least an hour before a scrub. May need to repeat if it is particularly bad. Hope this helps."

"Use a thick bleach such as blue container Domestos, leave for about 30 minutes to one hour, you will see the limescales peeling off on their own. It may not all come off in one go but try to do this 2 to 3 times on the same day or within 2 days. You can close your toilet for better result but it is not compulsory to close it, it is advisable as this will also reduce the inhalation of the chemical."
