Oren posted for all of us...

I would think a Snap-On large pry-bar would be the solution. Much wider blade. Get one with a striking head...

Left it for a few hours - a brilliant result - brown gunk had peeled off. Have used on all bathroom items since, with excellent results.

Muriatic acid is tough on skin and the fumes will burn your lungs but in the environment it disappears pretty quickly. It will react with the calcium or other metals in the soil and become salts. Certainly a rail car full would be a problem but a cup of it disappears pretty fast. I use it by the gallon in my pool.

Tried everything then came across Calsolve toilet descaler, about £15 on amazon. Fantastic, really works. Follow instructions including hot water. Sorted!

Vinegar may not be strong enough. Use phosphoric acid. Muriatic acid is likely to etch the porcelain.

We had two brand new toilets tht quickly began a discoloration at the water line in the bowl. We tried leaviang bleach in overnight but it didn't work for us initially. To finally get rid of it we used a commercial acid-based toilet cleaner that completely eradicated it. Now we drop in a cholorine tablet into the tank once a month and the stain has never occured again.

Hydrochloric acid works for me. I agree, if it's mineral deposits that accumulate at the water line, bleach won't work.

Actually, they are the same thing. Hydrochloric, muriatic, Salzsäure, all the same same.

Nope, muriatic is just the old name for hydrochloric.

Wrong.

Used for a lot more than just that.

And in general hardware stores.

And I'd buy it at HD, likely cheaper than at a pool store. People use it to adjust the PH of pools, I guess you could clean the tiles with it too.
