Yesterday, I was stripping blue anodising from a pair of wing buttons with some Mr Muscle (Same as Easy-off) It comes off really quickly, but there was just a little stubborn bit, so I left the buttons in a tub with the Mr Muscle for 5 minutes... well five minutes turned into 8 hours before I remembered they were in there.
Here's what they look like now

They are completely black, and in some places crusty, but it will not come off. So, any suggestions on how to get them back to the nice raw aluminium look I was hoping for.
