Dirty toilet - picture attached

[MrsJDornan]

Hi I've just moved into a new flat and the toilet is filthy - I've managed to get rid of all the dirt where the water is but I can't seem to remove the line, does anyone have any tips please as I'm running out of ideas and bleach

Harpic tablets are what I used to remove most of it, took a box (using 2 a night) but it worked just need this bit gone too and then a new toilet seat

Denture cleaner tablets. Put 2 in the toilet bowel and leave overnight. Trust me, you’ll be amazed at how clean and sparkly it will look!!

As a landlord I've seen many bad toilets.
Spirit of salts will definitely work. You can buy it from amazon. But make sure you don't breathe it in and leave it for an hour with lid closed😷

Black harpic is brilliant - buy a couple, put shed loads and down leave over night and repeat if necessary - keep some in the cupboard

I tried the bottle of cola (we got some with a Pizza delivery and none of us drink it)

It stained the limescale brown . It looked a hundred times worse .
