    I have very heavy black lime scale marks in the pan on our upstairs toilet. We use caustic to get rid of them but they come back within days. Our other loo is fine. Any ideas what it could be? :rolleyes:

    If its lime based as is likely you would be better with hydrochloric acid sold as spirits of salts.

    Is your wc cistern leaking constantly into the bowl?

    If it is really limescale, you need a lime-scale remover to get rid of it. these are usually acid cleaners. If you live in a chalky part of your country your shops will keep it in the household cleaners section.

    Over here they are sold as a kind of toilet cleaner, you need to use the brush to reduce water level, then squirt this thick liquid over the limescale and let it soak in overnight, before flushing and brushing. if limescale is heavy you may need to repeat.

    there are lots of other limescale removing products for use in the kitchen and bathroom. You can also use citric acid or other mild acids; but some acids remove chrome plating and tarnish brass so are not suitable.

    You can tell if you have limescale because it will also be in the WC cistern and round the taps and in the kettle.

    If you have limescale in the pan (or anywhere else) it is rough and absorbent so it traps dirt.

    Cleaners that remove or bleach the dirt but leave the limescale behind will not help much, since it will soon absorb dirt again.

    You can also test for limescale by putting a drop of vinegar on it, limescale will fizz if you do.

    If you have water pumped from private well it will probably contain more sediment and dissolved solids so will tend to stain more.

    If your other loo is newer then the problem could be that the old loo has a rough surface that the limescale is sticking to. In the long run you'd be better putting a new smooth loo in like the other one.
