Alibrite from Supercheap, but don't get it on yourself and wear safety glasses.

take it to an anodisers and get them to reverse it.

Lot of effort for a sprocket.

Surely buy a new one.......?

I use this method ....use a phosphoric acid bath at about 20 precent phosphoric acid to 80 precent water (1 gal. of acid to 4 gal. of water ratio) heat liquid to 190 degrees. then submerge part depending on size for 1 to 3 minutes.

I also use citric acid to clean rims

Oven cleaner is Caustic based ....

I learned that one the hard way when I mistakenly (don't ask ) used garage floor cleaner (caustic) to remove some rock hard mud'n'stuff from my wheels. The result wasn't pretty.
