Cleaning off the salts (the white stuff) does

OK! Salty water,

No, not salty water. I was very careful to *NOT* mention table salt
(sodium chloride) so that you would not confuse that with a chemical
salt (ionic compound created by mixing an acid and a base).

should be pretty easy to
remove! But it wasn't, it was more difficult to
remove than rust! Perhaps got intermingled with
the aluminum and/or coating?

The underlying metal probably looks like Swiss Cheeze (full of holes).
If the reaction products are mixed into the holes, they will be
difficult to remove by mechanical means. That leaves chemical means,
which requires knowing what has corroded.

Hint: Twang you spokes like a harp and listen for the tone. If you
find one that produces a dull thud and is obviously loose, look for
metal loss (though corrosion) around the spoke hole. This might
prevent having the spoke rip out of the rim when you put a load on it.

I never gave this much thought or actually
I did give it some thought and that thought was
I didn't know the answer

The quality of the answers you receive are directly related to the
quality of the information you provide. I've seen no accurate
description of what is corroded or any maker or model numbers. Since
you've also avoided answering my questions, I give up.
