Super-strong loo cleaner?

[octopusrus]

One of our loos has staining that I've never been able to shift since we moved in - despite trying a few things and plenty of elbow grease. Can anyone recommend a strong product I could try next?

Try the harpic cleaner in the black bottle. Scoop out as much water as you can from inside the bowl. Squirt cleaner onto the stains and leave for a couple of hours. Once flushed it should do the trick.

Failing that you could try really cheap full sugar coke. Similar method. Never tried it myself but a friend said it works really well.

Thank you will give the Harpic a go - I've tried the Coke but I'm sure it actually made it worse!!

Have you tried those white magic eraser blocks?

If you pump your loo brush (I know they aren’t liked on here) into the u bend entrance repeatedly you’ll be able to get rid of most of the water in the loo so the cleaner will work better.
Mine was awful when we moved in with limescale. But it’s got better with scrubbing (I just use any old cleaner) and regular cleaning.
