Harpic 100% Limescale Remover - does what it says on the bottle.
Works a treat.
Sadly I used that - it hardly knocked a dent in it I'm afraid!

As for the other acid-based products mentioned in this thread, are
they things readily available in B & Q etc.?

Builders mercahnts for brick acid, or a good hardware shop.

Don't expect it all to go instantly.It takes time to dissolve decades
of urine, limescale and ****.

Someone mentioned phosphoric acid. I think thats 'jenolite' rust
remover. Brick acid is about 30% hydrochloric. Most descalers are
sulphamic, but any acid will ultimately crap all over carbonates,
apart from carbonic acid!

Other acids you can get are formic - I think Kilroc uses that..and
sulphuric. That's generally for specialised sanitary cleaning type
operations. Or car batteries of course.

Sulphuric can attack the glsae on a WC pan.


Last I heard only nitric/sulphuric mixed could do that..

Howevr, it pays to be careful.
