We don't have dirty toilets BTW, there are lots of other cleaners,
including "mai cham" (literally hot water), which is a dilute muratic
acid solution.

That will etch the surface of the porcelain, which will cause
particles of defecant to stick to the surface. It's much like using a
chemical sandpaper.

I don't think that's correct. I don't think most acids will attack
porcelain.

This is all I could find. It isn't clear what the relationship between
"porcelain enamel" and the porcelain used in bathroom fixtures is.

acids are what's used to etch porcelain bathtubs for "refinishing" with
epoxy paints. even leaving chlorine bleach solution puddled on the tub
surface will etch it,I found that out the hard way.
