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.

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

Says in post 1 that it's only 18 months old. If industrial cleaner has been use on it, then maybe the enamel has been damaged.

The Sainsbury Toilet Cleaner / Lime Scale Remover I mentioned above is the best thing I've used - better than limescale remover. One of life's rare bargains at only a pound a bottle (I'm not on commission)

To work on it after soaking use one of these cleaners filled with some of the Toilet Cleaner - but be sure to wear rubber gloves... and watch your eyes, glasses would be a good idea...

They sell them in Sainsbury's (couldn't get their link to work)

If that doesn't move it, it's not lime scale.

Must pay more attention. :/

Might be due to faults in glaze.

If people with bad diabetes can stain the pan badly, especially if they don't flush after use.

 

[scoz]

Always have done

Thanks I will try this as well, as you say it may not be lime scale because there is never any fizzing as with limescale when the cleaner are used, it is just off white colour but a slightly rough surface.

 

[scoz]

No it is a just off white colour

It's calcified pee. Nightmare.

No don't use wet & dry as you will scratch the glaze surface. Some descalers can ruin the glaze surface so be careful and don't leave in for too long.

TB services is spot on. Leaving pee in the loo without flushing is the cause. I have got it off in the past with a high pressure jet washer and tiny nozzle.

it could be lime-scale especially if its on the water line try "one shot drain" cleaner from B&Q if it is lime scale this will remove it.
however it also could be the glazing that has that has worn and all cleaning will do is give you a temporary fix.
