Aluminum + Bleach Still Safe?

 My father accidentally left an aluminum pan in a basin with water and
bleach.  (The cleaners filled the dish basin to bleach it and forgot to
empty it, and then he put the pan in it to soak.)

It acquired metallic "fur" spots which I scoured off, but there are
still black spots on the aluminum.  Is this merely discoloration, or
does it make the pan unsafe to use, and if so, what is the best way to
recycle it?

(If this were a think, cheap pan I would just throw it away, but this is
an aluminum pot from eighty years ago or so, so it is fairly substantial.)

Since it's aluminum, I'd throw it away anyway or use it for non-

Last I heard that was questionable (see below).  At any rate, my father
is 96 and has been eating out of these pans for over sixty years.  His
brain is still sharp, so I figure a couple of more years aren't going to
make a major difference.

I was more concerned with whatever compound was formed when aluminum and
bleach combine, and whether that was toxic.

A number of environmental factors have been put forward as possible
contributory causes of Alzheimer's disease in some people. Among these
is aluminium. There is circumstantial evidence linking this metal with
Alzheimer's disease, but no causal relationship has yet been proved. As
evidence for other causes continues to grow, a possible link with
aluminium seems increasingly unlikely.
