getting rid of limescale in the toilet.

10 Jan 2025

Unsightly dark stains in the toilet bowl that your normal cleaning product won’t shift?


If the actual bowl of your toilet looks brown you are probably dealing with limescale. It’s a build up of mineral deposits from the water - a common problem in the UK. Over time it can turn brown due to iron in the water and also because a chemical reaction occurs when urine comes into contact with limescale.

BUT don’t despair! Our 4 top tips for a shining bowl use products you may well already have in your kitchen. Here’s what you can use to get rid of limescale in the toilet: 



1. dishwasher tablets.


Yep - dishwasher tablets have so many hidden uses. If the stains aren’t too bad just drop a tablet into the bowl and leave it overnight.

Stubborn stains can be tackled using your dishwasher tablet a little like a pumice. Pop on some gloves and gently scrub the hard water marks directly with the tablet. The dishwasher tablet will start to dissolve the limescale and you can continue until all marks have disappeared. It’s a lucky coincidence that smol dishwasher tablets are designed to tackle hard water marks so the limescale deposits in your toilet bowl are completely fair game. 


2. cola!


This fizzy drink actually contains something called phosphoric acid which is good at removing limescale and urine marks. 


Just pour a one litre bottle into the bowl and leave it in there to work for a few hours. It should dissolve the limescale deposits. Some people also like to sprinkle bicarbonate of soda around the bowl before pouring in the coke just for a more intense effect. 


Remember to flush your toilet after a few hours and admire the results! 


3. white vinegar.


Pour one litre of clear white vinegar into the bowl - aiming it all along the sides and allowing it to run down into the water. Leave this to work for a few hours or overnight if possible.


You can scrub the toilet bowl with a toilet brush after the vinegar has worked its magic and then flush the toilet when you feel all the limescale has gone

4. citric acid.


This is a good option if you don’t like the strong smell of vinegar, in fact citric acid has quite a pleasant fresh smell so is commonly used to clean toilets. 


Mix two to three tablespoons of citric acid powder with one litre of water – always add the water to the bucket before the citric acid to avoid splashes. Then pour it into your toilet bowl and leave for a few hours. 


Again… flush and admire the clean bowl! 

how to remove stubborn limescale toilet stains.

If the methods above aren’t quite removing it all you can effect a stronger reaction by removing the water in the bowl. 


Plunge out as much water as you can and then pour in your chosen cleaning solution and leave it overnight. Without the dilution of the toilet water you should find the product gets to work directly on the limescale. Then scrub with a toilet brush in the morning and flush.


Once your toilet bowl is gleaming remember to keep on top of the stains because the limescale deposits will build again.
