Help......I've made things worse cleaning my toilet.

[Tolkienista]

I've lived in my house for a year and I've inherited what i now realise is a toilet with extreme limescale.
Thought I'd have a go today at removing it myself with tools around the house and general cleaning products, I've ended up making it much worse as you'll see in the pictures......I used a plastic scraper to get some of it off, but it looks far worse now.

What do I need to buy that will actually work?

Citric acid also works wonders on descaling kettles and cleaning shower screens. So it's a handy thing to have in stock if you're in a hard water area.

Coke worked on mine.

Following this with excitement 😂

Kilrock K, wondrous stuff

Another vote for citric acid. Use it for everything. Shove lots in toilet, leave overnight, scrub, flush, done and less chemically nasty than lots of other options. I have 3kg bags of the stuff. Also excellent as washing machine cleaning agent.

Not soda crystals. This is a carbonate (like the limescale). If you put them in acid they will fizz. GCSE chemistry: dilute acid plus carbonate = salt plus water plus carbon dioxide.

you need acid. Vinegar is too weak. The thick limescale liquid will do it, or viakal, or those harpic tablets. Putting boiling water with a kettle descaler sachet is chemically sound, but you may crack the toilet bowl
due to the temperature shock. Hydrochloric acid will work, but it’s a bit high risk in terms of fumes and spillages.

my advice is to use a susbtance you can get in the supermarket which has the words toilet and limescale on the label. Some of the home-remedies included here are pointless, others are potentially dangerous.

I've seen people using a pumice stone in it if it's really stubborn.

Black harpic tablets followed by a rubber glove with a green pan scourer

Best option imo

No it won't. Soda is alkali and vinegar is acid, they will neutralise each other. This does nothing except fizz a bit when you mix them.

Another saying spirit of salts. It's user to get paint off bricks. Amazing stuff but I use a gas mask.

Well it worked for me!

Those harpic tablets didn't even touch the limescale in my toilet!

Harpic loo cleaner (black bottle) plus two of the Harpic tablets overnight.
took two nights but I cleaned a toilet in one of DD’s rentals that was easily the worse one I had ever seen. It was brown with really thick limescale.
Then used a Brillo pad on it and the results were spectacular.
