How To Remove Limescale From A Toilet

Noticed a chalky white or brown substance starting to build up in your toilet bowl or around the rim? Unfortunately, you’ve probably got a build-up of limescale forming. Limescale is a build-up of calcium carbonate formed by the calcium and magnesium ions found in hard water. Houses in areas with a hard water supply are therefore much more susceptible to limescale problems.

The good news is that you can remove limescale from a toilet very easily and get back to having a shiny clean toilet bowl. Read on to find out how to make your own toilet cleaner at home, or check out our recommendations for the best shop-bought products.


Make your own toilet cleaner



  • - Half a cup of baking soda
  • - 250ml white vinegar
  • - ½ a teaspoon of tea tree essential oil


  1. Mix the vinegar and tea tree oil together in a spray bottle.
  2. Spray the inside of the toilet bowl, the seat, lid, and handle. Be sure to cover the underside of the toilet rim too and leave the mixture to work for a few minutes.
  3. Drop a few pinches of baking soda onto the surface of the toilet bowl and scrub thoroughly using a toilet brush. 
  4. Rinse away the cleaner and the dislodged limescale. 
  5. Repeat as necessary until your toilet gleams like new!

This cleaning solution is actually multi-purpose, so you can also use it to scrub out your bath and sinks too. The acidity of the vinegar helps to break down the calcium deposits, while the baking soda provides the friction needed to help you scrub away easily. 


How often should you clean your toilet?


Try to clean your toilet at least once a week to prevent limescale from reforming, and you won’t always need to use as much elbow grease in the future. Weekly cleaning also helps to keep your bathroom hygienic and reduce the spread of harmful bacteria like E. coli. 


What are the best toilet cleaners in the UK?


Of course if you don’t want to make your own toilet cleaner, you can always turn to shop-bought products designed to do the job for you. Here are some of the products we’ve found to be most effective for deep cleaning toilets and other areas of the bathroom. 

  • - Viakal’s limescale remover spray has a plethora of good reviews, comes in at a low price, and gets an endorsement from Mrs. Hinch herself!
  • - If buying ethical products is important to you, EcoGurus Limescale Remover is biodegradable and phosphate-free. However, this is reflected in the price. 
  • - Harpic Power Plus toilet cleaner is often highly recommended for effective cleaning of toilet bowls above and below the waterline. 
  • - Soda crystals are a go-to product for many people as they are designed to prevent and break down pipe blockages, and can be used in sinks, baths, and other drains too. Dri Pak is often the brand mentioned here, but any equivalent own-brand product should do the job too. 
  • - Toilet rim blocks are effective at deodourising and disinfecting the toilet bowl after each flush, but must be replaced regularly. Some products claim to help prevent the buildup of limescale, but this has not been definitively proven. 


Limescale and hard water


Ultimately, limescale is caused by your water supply. Specifically by the minerals in hard water that get left behind once the water has dried. This is why hard water areas of the UK suffer more with limescale than soft water areas, so if you want to take action to stop limescale from building up again in the future then softening your water is a great way to do that. 

A water softener can be easily installed to filter your water and stop these minerals from building up on your bathroom appliances.
