After ten minutes, I see that buttery white stuff again.

The unknown white lard 'seems' to be where the rust was heaviest.

the white crud is from letting the pink slime dry. you have to really
scrub it off, then it's gone for good.

When I used to do my aluminum wheels, the navel jelly would dry to a
whitish finish. I then hosed it off.

Thanks for explaining what it is.
I wasn't sure - but it kept showing up.
It looked and felt like lard.

Now I know ... it's naval jelly dried up.

Thanks!

from a bottle of the loctite naval jelly:

"do not use on aluminum."

"If left on too long (hardens), apply more Naval jelly rust dissolver to
remove"

I'm still not sure what the white crud itself is- maybe the goo that keeps
the stuff slimy?

Naval Jelly and similar are about 1/3 phosphoric acid, dissolved in
water, with a percent or so of thickener (the N.J. MSDS says
"polysaccharide, proprietary" - might be something like a xanthan
gum?).

Phosphoric acid itself is a white / crystalline solid at room
temperature, melting to a viscous liquid at roughly body temperature.

Considering the concentrations involved, I'd guess that the "white
crud" or "lard" is mostly phosphoric acid, left behind when the water
evaporated. You could be seeing the polysaccharide gelling agent as
well but there isn't all that much of it by volume.

Try warming the crudded object gently to somewhat above body
temperature... if the crud turns to a clear liquid, this would suggest
that it's the phosphoric acid.

The naval aluminum jelly, is the same product, with reduced concentration.
I like speed of regular.
