I wouldn't try cleaning aluminum with anything except distilled water or organic solvents and they aren't going to do anything to those spots. They will clean any organic gunk off the coin but not the discoloration. I don't think anything short of an abrasive would work.

Unfortuately sort of true. Aluminum is a metal that coats itself with it's own Oxidized layere that actually protects the rest of the metal from further distruction. Removing it only exposes the rest of the metal to a new attack of Oxidation.
There are really a lot of solvents on the market for cleaning Aluminum though and available at most hardware type stores like Home Depot, Menards, Ace, etc. Many use such solvents on houshold Screens and it really cleans them well but a layer of Oxydation returns fast.
IF those tokens are not to expensive, you may want to try a fast dip such solutions but remember, the outer layer of the token will be stripped.
