In the long run, knowing how to descale a toilet cistern can extend the life and efficiency of your toilet, so it’s well worth doing. And once you’ve learned how to remove limescale from a toilet cistern it’ll be easier the next time you do it. Follow this step-by-step guide for great results.
Wear protective gloves and old clothing:
- Put on protective gloves and old clothing before you start to protect yourself.
- Remove the lid from the toilet cistern to beginning cleaning.
- Lower the level of water – either by turning off the water supply to the toilet or adjusting the float height valve.
Pour cleaning solution into your cistern and leave for at least half an hour
You can use a specialist cleaner like citric acid, or try vinegar if you want a more natural approach. Make sure the solution covers the limescale, and leave for at least half an hour (or longer if you can).
Scrub thoroughly with a brush
Scrub thoroughly, rinse and repeat as necessary. It’s a good idea to descale a toilet cistern on a weekly basis to prevent limescale from building back up.
