Toilet limescale is caused by hard water with high amounts of dissolved minerals. The minerals build up over time and leave unpleasant stains in the toilet bowl.
Toilet bowls covered in limescale are often left in a sorry state as many households are unsure of how to clean them. Luckily, a mum has taken to social media to share a cheap product that gets the job done.
Toilet limescale can build up within a few days, and bleach only changes its colour. To remove it, a cleaning expert has suggested using acid-based products like white vinegar.
