When I say "schmutz", I mean hardened fecal schmutz.

A while back Harpic released an acid based bog cleaner

I've found if the limescale is stained at all it takes an awful lot
of bog cleaner to shift it -- whiten the limescale with bleach first.

There's an American product called CLR (calcium-lime-rust) specifically for
such stuff.

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.

Lemon is a nasal desensitizer. Add lemon scent to anything and all
you small is lemon. That's why there are so many "lemon fresh"
products on the market. For an example, put a lemon under your nose,
while biting into an apple.

I was mostly serious. It's a difficult problem, but attempts have
been made by people with more imagination than me.

Something showing two bottles of whatever, mixed together, and
creating a mushroom cloud, might be effective as a general warning not
to mix anything together. Whether they understand the point, might be
debatable. I suspect the difficulty of the problem resulted in the
ban.

You're getting our rejects and counterfiets. I never realized how bad
they can be until I bought some fake Duracell batteries at a local
thrift shop. Some had leaked in the package, which should have given
me a clue.

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.

The by-product from air oxidation of lemon oil (d-Limonene oxide) is one
of the most allergenic chemical known. It forms in part-used bottles of
lemon-scented products and I have seen the horrible results of the
sensitisation it causes. (One of my work colleagues lost most of her
facial skin to it)
Even if you aren't allergic to it, other people may be, so please don't
use it.

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.

Which acid or acids? Decades before I saw "Breaking Bad", I knew that
hydrofluoric acid attacked glass and porcelain. But hydrochloric?

Okay, but we're talking about acids directly applied to porcelain.

I read that vomit can etch porcelain tile. that's HCl.
saw mention on Google that phosphoric acid etches porcelain.

Googling.... See the "acid resistance" and "alkali resistance"
sections at:
<http://www.porcelainenamel.com/pei503.htm>
The degree of attack by acid solution on porcelain enamels
appears to depend less on the type of solution than on its pH.
"Chemical Resistance of Porcelain Enamel at various Temperature
Levels"
<http://www.zurn.com/operations/specdrain/pages/TechnicalInformation/Receptors/OF52.pdf>
Looks very good for both base and acidic. However, hot ammonium
hydroxide (common household ammonia) looks like a potential problem. I
usually mix the stuff with hot water when washing the floor and dump
it in the toilet. It's not concentrated, but it might cause a problem
because it's warm.

I used a rust remover that seems to give good result.
Rinse after with water to remove residue.
