I usually do light cleaning with window cleaner that has a little vinegar in it.
Found this link a few weeks back:
Looks like alka seltzer really works wonders. Not sure what the Pentacon/Contax metal is - looks like nickel-plated steel(?), but I suspect the alka seltzer would work as well with aluminium.

Flitz metal polish is, in general, a good product for cleaning/restoring older metal parts and not damaging them.
