I have had success with the most hardcore kind of Harpic - think it was this one.

yes, denture tablets will do it. Put a bucket of hot tap water into the bowl first so the tablets dissolve and work faster. (not boiling water or it may crack). You can put two tabs in if badly stained. Leave it for several hours. e.g. do it just before you go it.

Use the brush more often

Other ideas on here. If you have hard water I am very keen on the Parazone Bleach Blocks.

Denture tablets are brilliant for toilet cleaning.

caustic soda works, its lethal though.

My mum scooped, then soaked the water up. And then used anti lime scale stuff and lots of elbow grease . We'd just moved in too.

You have to remove the water, otherwise whatever you are using is being diluted, and therefor less effective.

Scoop the water, don't siphon.

Yes scoop out all the water - it takes a while but is worth it. Then you can usually remove the stain quite quickly with jif or limescale cleaner.

Caustic soda will do it. Very dangerous but you put it in the loo and it fizzes and dissolves the limescale. You need to buy it in small amounts so that you can use it all and not have half-used containers of it hanging around the house.

Try pouring a bottle of coke down the toilet - MIL swears by this and always has a gleaming toilet Can't say I've been brave enough to do it - I prefer my coke with brandy tbh

Apparently dropping one of those magic erasers in over night works. Not tried it personally though so can't promise.

Regarding getting the water out: you can often force it past the u-bend by sort of pumping it with a loo brush. I'm sure Kim and Aggie would suggest coke and a pumice stone.

you can scoop (or push out with the brush) the water if you are going to swab or scrub the stain.

Howver if you are using denture or Harpic tabs, you must have water in it, since the stain must be immersed in the mixture

I'm reading this and taking notes ...shows how exciting my Saturday night is

Harpic Power plus tablets. Let one sit in the bottom of the toilet for 6-7 hours, then flush, it will be completely clean with no scrubbing!

I sympathise, I have this problem...
I tried coke and it just stained it all browner! I tried the strong harpic in a black bottle and it didn't really work.
A pummice stone and scrubbing worked absolutely the best and doesn't involve evil chemicals, but it wouldn't get the stain out of the groove bits at the bottom.
Then we came across something called 'Killrock'. On the bottle it says 'Killrock - the one that works', and it does. We got it in Aldi but I'm sure you could get it elsewhere...

Don't use caustic soda - my friend did and it ate all the way through her toilet and caused a bloody flood!

Denture tablets are the best thing IMO.

has no one mentioned vinegar yet?

I'm stuck with mine as well. Have tried several different things but nothing is shifting it.

Berti even the Harpic tablets?

we use dishwasher tabs at work… leave it overnight… might take a few applications but deffo works…

Yep, tried a harpic tablet the other night, nothing. Although I didn't get a chance to scrub it first thing after it was flushed, but even scrubbing the same day didn't touch even the top layer.

I got one of those rim block things on an offer with the tablets which claims to eliminate limescale too, so have that in, will try and do the tablet again at some point and then get the brush on it in the morning.

Dishwasher tabs? Interesting. I have a big pack of those that I could spare a couple!

Oh actually, I tell a lie, it did touch the very top layer, as in the part where the water line is, that started to show through whiter

Perhaps harpic tablets one by one on consecutive nights??

If you have some on the waterline and around it really is worth a try with a pummice stone, it works with only a light scrubbing, it just didn't work for the 'nooks and crannies' in my loo bowl.
Why anyone would design a loo bowl with nooks and crannies is really beyond me though...

tried white vinegar? i prob don't have water lines as bad as you buy i usually stock up on white vinegar and just put a load of this down, costs about 99p for a bottle and then this'll do the trick if it's given proper time to do it's magic.
