Hey, I want to cover my rear against law suits. Check out the pH of any Oven Cleaner. I looked at three on-line and the pH of the ones I looked at ranged from 11.5 to 14.0 (the maximum possible in water!). That is enough to dissolve SKIN and when it does it "feels slippery" because it is dissolving the skin. Sooo, wear goggles and rubber gloves; maybe a rubber apron too! Don't be surprised if you have many holes in your clothes after you wash them! I have my doubts about using a strongly basic solution to remove the effects of a basic treatment. I guess I would try just soaking the parts in white vinegar and then buffing them when dry and then soaking them again, drying again and buffing again etc until the coating is gone. Maybe oven cleaner will work but it is dangerous and I am not sure it will work so use safety precautions if you use it and let us know what happens. My best guess is that oven cleaner may remove any blackening or color of the anodizing, but not the underlying dull white layer and will actually increase the white oxide coating; thin pieces may hole-through with prolonged exposure to strong base (high pH above 10).
