Any ideas what happened or how to fix it (hopefully something other than making them all gray)?

Aluminum is susceptible to oxidation if exposed to strong acidic or alkaline cleaners and polishes unless the surface is anodized. What polish did you use? I recommend getting a cleaner and a polish specific for use on aluminum.
