I've never EVER had any signs of any damage to even one toilet in all those years.
In fact the vitrified clay china glaze finish will look like brand new again.
Naturally handling any chemicals with care goes without saying and it is corrosive but nothing to scared of if handled properly.
I will admit, years ago when wooden toilet seats had chrome plated hinges screwed onto them I have seen a little corrosion on the wood screws a couple of times.
I take one quart of water out of the bowl, slowly pour one quart of Calcisolve down through the over flow tube so it goes down through the rim jets on it's way to the trap-way where it brings the water level back up to normal, close the toilet seat lid, and sometimes crack open a bathroom window.
The next day the toilet will be brand new again.
However in my area there are no porcelain water closets, just Vitrified clay china.
But hey, don't do it the easy way if you don't want to, don't matter to me. I'm just sharing my almost 40 years of repair plumbing experience,, take it or leave it. ![icon_biggrin.gif](upload://iKNGSw3qcRIEmXySa8gItY6Gczg.gif)
Anyway, like I said sounds like a plugged soil pipe to me.
