How to Remove Limescale From Toilet

Posted by ilker Duymaz on

One of the common challenges homeowners face in maintaining their bathrooms is tackling limescale build-up in toilets. Limescale, a hard chalky deposit, is a result of hard water and can cause unsightly stains in your toilet. Besides aesthetics, prolonged limescale build-up can also damage the toilet and reduce its lifespan. Fortunately, there are effective ways to combat and remove these stubborn stains. Here's a guide to help you restore the sparkle in your toilet.

How to Remove Limescale From Toilet

1. White Vinegar

White vinegar, a staple in many British kitchens, is a natural and effective way to tackle limescale. To use:

  • Pour undiluted white vinegar into the toilet bowl until the limescale is submerged.
  • Leave it to soak overnight.
  • Scrub with a toilet brush and flush. The acidic nature of vinegar will break down the limescale, making it easier to remove.

2. Lemon Juice

Another natural alternative is lemon juice, which contains citric acid:

  • Cut a lemon in half and rub it directly onto the affected areas.
  • Allow it to sit for a couple of hours.
  • Scrub with a brush and rinse. The limescale should come off with the added bonus of a fresh, citrusy scent.

3. Commercial Limescale Removers

If you prefer a more robust solution, there are many commercial limescale removers available in the market. Always read and follow the manufacturer's instructions:

  • Apply the product directly onto the limescale.
  • Leave it on for the recommended time.
  • Scrub, rinse, and flush.

Ensure the product is safe for use on toilets to avoid any unwanted damage.

4. Bicarbonate of Soda and Vinegar

This combination can work wonders:

  • Sprinkle bicarbonate of soda (baking soda) onto the limescale.
  • Follow by pouring vinegar to create a fizzing reaction.
  • Allow it to sit for an hour, then scrub and flush.

5. Regular Maintenance

Prevention is always better than cure. Regularly cleaning your toilet and using a mix of vinegar or lemon juice can prevent limescale build-up in the first place. Set a routine to clean your toilet at least once a week.
