I use that on my motorcycle wheels ... but it's a mildly
abrasive paste and therefore won't penetrate into tiny
cracks and crevices caused by salt corrosion. What I need
is some kind of water-like liquid chemical that will
completely dissolve out whatever corrosion is there.
Otherwise, if I try to coat the part in any protective
paint or whatever, the damp hidden pockets of corrosion
will just continue to eat away at the metal plus breech
the coating.

I guess the corrosion is aluminum chloride, sulfate
and hydroxide mostly ... maybe with a speck of bromide
thrown in. The chloride and hydroxide are hydroscopic
and thus attract moisture from the air - causing even
more corrosion.

Hmmm ... I know the people who chrome aluminum 'pickle'
the metal first in some sort of acidic bath to remove
all traces of corrosion and oxides. Dunno WHAT kind(s)
of acid or how strong however ... pool acid will just
eat the hell out of aluminum, vinegar doesn't seem to
be active enough.


Hands down; Mothers Mag Wheel Polish.

Help !

What chemical products seem to work the best for removing
that sticky white salt/moisture corrosion from aluminum
parts ? If I could get it off then I could coat the parts
with chromate, zinc paint, urethane or something ...
