Can't vouch for it personally, but I found a page where a guy described de-anodizing some bike frame parts with good results using this stuff: http://jestcoproducts.com/index.php?act ... oductId=37

We used EZ Off Oven Cleaner (though any strong base should work) in one of my advanced metal working classes. Spray it on, let it sit for a few hours, repeat if needed. Be careful not to pit the Al though. Try it on a few cheapo anodized keychains first.

The real trick is polishing afterwards. Maybe hit it with steel wool and something like Brasso

steel wool or would scratch off the painted lettering though, wouldn't it?

Hard to say without knowing what it actually is (enamel paint, screen-printed UV ink?). I believe spray oven cleaner is essentially lye-based, if that helps any.

I thought Drano was just NaOH/lye/caustic soda. Have to go look.

If all else fails, you can order a skin from StyleFlip. :?

Oh, and maybe a finer grit steel wool than your typical kitchen variety, maybe 800-1000 grit (it's in powder form). The letters are etched in, correct? (I have a styleflip on, so I've totally forgotten)

You could also look at some finishing grade scotch bright (the machine shop variety), it comes in wipes and works great on aluminum. There is also brass wool which may be better on some grades of alumium

sand blaster. I cleaned my 1200's technics like this. It removes lettering too though. But then you can brush it with scotch brite pad to give effect.

Then I powder coated them.

Yeah, because people are way more likely to have one of those (and the space to use it in) sittin' around, than they are a can of oven cleaner. ;)
