how to remove alkaline battery residue

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?

I recently discovered that caustic soda in an ultrasonic cleaner is capable
of etching the glaze off of spark plug insulators.

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.

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.

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.

Levels"

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.

hell,don't pour any down your throat.
carbonated sodas erode(etch) teeth enamel.
I had to stop drinking it because it was giving me heartburn.
I'm just an old fart....

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

Between the combination of the hotest day in many years and really bad
batch
of alkaline batteries, I have several devices with a crystaline residue
from
the batteries leaking.

Besides brushing with a succession of stiffer brushes, is there some
chemical
that can safely remove it? It's all on metal contacts in plastic, but some
are
surrounded by anodized aluminium.

Thanks in advance,

Geoff.

To help restaurants, as part of the "stimulus package", everyone must
order
dessert. As part of the socialized health plan, you are forbidden to eat
it. :)
