Limescale or what?

[scoz]

In the bottom of the toilet around the water line is what I thought was limescale,but no limescale cleaners have moved it. The toilet is thoroughly cleaned every week but nothing shifts it. Bleach fades it so it is less noticeable but even industrial limescale remover does not shift it.
I do not believe that it is limescale as there is no fizzing and bubbling when limescale removers are used. The surface is rough like feeling fine sandpaper so I am at a loss what it can be. I do not want to change the toilet as it is only 18 months old but if no solution is found then maybe I will have to. By the way I live in a hard water area in West Yorkshire.

Get some wet and dry sand paper and see if that will move it. But don't be too rough

 

[scoz]

Ok will try that.

Then use White vinagar leave as long as possible to soak, may take a few attempts though.

 

[scoz]

Will try that as well, Thanks

We are in a hard water area and get the very same. I use viakal and leave for an hour, then don the old rubber gloves and rub it off with nylon scotchbrite cloth(green stuff)........works a treat.

fingernails get under it, but dont bite them for a day or so

Great, I will buy some as I have had limited results with the other suggestions. Thank you.

Try a pumice stone (cheap one from tesco)

Brick acid.

 

[scoz]

I have tried morecrete but that did nothing, so I am at a loss as to what it is as it does not fizz like limescale does.

Empty the pan of all the water before trying anything

is it dark almost black creeping down the back of the bend ?we found using toilet cleaners diid this to ours and we went back to using bleach

Sainsbury's bog standard 'Toilet Cleaner / Lime Scale Remover' - costs a pound a bottle, and it's brilliant stuff. It's in a blue bottle and has "5x more powerful than bleach" on it.

Remove the water from the pan and soak the pan with the cleaner, and leave overnight.

If it's built up you might need to repeat a couple of times, i.e. leaving it to soak overnight.

If its an old wc then the enamel may have perished and no amount of cleaning will solve it.
