Coffee stains

[Lee Schierer]

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
Alcohol
soap & water
water
Loctite Solvent
WD-40
Automotive wax
various oils
Power Ball cleaner
Windex

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.

Imagine what the inside of my stomach looks like from drinking coffee every morning!....I am going to try muratic acid and alka seltzer:(
