As all disclaimers say: Test in a small area first. But if you google alloy and oven cleaner, you won't see stories about damage. Just "I heard" warnings. Some say rubber will be affected, other say they have been using it for 30 years with no problems. If you're worried, then don't.
I used Aircraft Remover at $10/bottle as well on my aluminum wheels. I felt like I should have been in a hazmat suit. Thank god I'm too old to reproduce now. The Aircraft remover and the Oven cleaner both did just about as well, and the oven cleaner was cheap enough to use for multiple coats. Plus I clean with it every other week in the kitchen. I'm afraid to reuse the Aircraft Remover after just one application. Yes, it was better, but not by much and I'm not sure it was worth it.
