Title: Removing anodized finish.
Post by arteacher on 04/30/12 at 11:11:00

I have some small parts that have been black anodized and would like to remove the anodizing. I tried paint remover and it didn't work. Any ideas?

Black anodize or black hardcoat?
MIL-A-8625 (hard coat) is exactly that. Hard. Like 60 Rockwell hard.
I've even tried blasting it with 80 grit aluminum oxide and it doesn't flake off. Almost nothing, short of chemically stripping it, will phase it.

I'd bring it to a plating shop to see if they'd strip it.
What's the part if you don't mind me asking?

Aluminum handlebar extenders. And it appears to scratch off easily.

Ive had good luck removing anodizing with gasket remover.

I remember I had some purple anodized bars on a dirt bike back when those colors were cool. It didnt last long and I decided to experiment with some chemicals out of the cabinet and If I remember correctly the gasket remover did the best job.

Easy-off oven cleaner in the yellow can. Wear gloves and spray it in a well ventilated area. Shouldn't take more than 10 minutes or so to get down to bare aluminum. You'll need to polish the part afterwards though.

Would soaking the part in vinegar do any good? It'd a good rust remover.

Unless someone can't tell if it is actually anodized...
If it will peel off at all, it's probably not anodized.
