We had an accident here at work. Some coffee got spilled on some freshly anodized aluminum parts. The parts were wrapped in paper and by the time they were unwrapped, the pieces are all stained where the coffee got throught he tissue paper. We can't get the stain off.

We've tried:
Lacquer thinner
soap & water
Loctite Solvent
Automotive wax
various oils
Power Ball cleaner

Anyone have any experience with coffee stains on aluminum?

I am not sure how well it will work, but I have managed to remove stains from stainless steel using foaming stainless steel appliance cleaner. I am not sure how it will react to aluminum tho...

You may have to do what I did with a shirt many years ago - stain the whole thing with coffee. Probably not practical for your anodized aluminum, but it made a nice light coffee colored shirt.
