Default Removing Annodization (without sanding)

Does anyone know how to remove annodization (sp?) from aluminum, without sanding?

IE - a chemical process that would work for a rather intricate piece of metal?

I've heard that oven cleaner will work.

See the PM I sent you..

These hosts use different aluminum alloys, DON'T use oven cleaner....I've tried.

Although not exactly hand/machine sanding, but still along the lines of sand, if you have yourself or know someone who can let you use a sandblaster, that gets rid of anodization very fast and very cleanly.

Ive personally never heard of chemicals that can remove anodization, if anyone knows Id love to hear about it too.

Oh lol - I missed your cautionary note before trying it myself.

That said, oven cleaner stripped the anodizing almost instantly!

Oven cleaner contains lye, which should eat aluminum and oxides thereof. Make sure you rinse it really well.

Lye is the trick. I use it to remove anodizing and it works awesome.

Um, is there any reason it should be such a big secret that it can't just be posted?

..dont forget lye eats aluminum too.. thats what I heard, and eventually I will try it on both! :-)
..and I sure hope you dont have lye in oven cleaner?!? wtf! lye is probably the most dangerous chemical you can easily buy!
