Default Removing anodization?

I've heard that you can remove the colors of anodization from aluminum by spraying oven cleaner and scrubbinbg it off. I tried it and it didn't work. Maybe I'm using the wrong brand, I tried Eazy Off lemon scented foam spray. I also tried paint remover, but that didn't work thanks to the helpful people at Home Depot. Anyone have an easy solution?

Default I did this about 15 years ago.

I used a heavy duty oven cleaner and some steelwool. It took several spray coats and some hard scrubbing. Afterwards I used aluminum polish. These days oven cleaner may not be as harsh. Good luck.

15 years ago? Jeese, I bet those chemicals would get you thrown in jail nowadays. Anyway, thanks for the tip. There's got to be a way.

You have to use the Outdoor breeze scent instead of the lemon.

OK I'm kidding. The trick is to let it soak. I use liquid draino instead. MIx a small amount 50/50 with water and let it soak. You'll see vigorous bubbling once the color begins to come off. Then just rinse, dry, polish!

Default Of course you will lose the corrosion resistance.

Anodizing is not just about coloring aluminum. It provides a corrosion resistant finish and increases the surface hardness. You will go from a tough, maintenance free surface to one that requires polishing to keep shiny.

The old Easy Off in the yellow can works. Just did some parts this week. Don't leave it on too long, it wil actually eat aluminum.

I just got through removing the anodizing from 3 cars worth of aluminum... not fun. Get EZ off heavy duty, spray it in a cheap pan or something, and let the pieces sit in it. I found that the anodizing strips off different parts at different rates, so be careful because it will discolor the aluminum if you let it sit too long.

Thanks. I don't mind it kind of dull. Has an industrial look, better than purple.

I'll try that too if the EZ Off doesn't work that well. Anyone else?
